I've completely redone the ethos InputManager and ruby to work on
HID::Device objects instead of one giant scancode pool.
Currently only the udev driver supports the changes to ruby, so only
Linux users will be able to compile and run this WIP build.
The nice thing about the new system is that it's now possible to
uniquely identify controllers, so if you swap out gamepads, you won't
end up with it working but with all the mappings all screwed up. Since
higan lets you map multiple physical inputs to one emulated input, you
can now configure your keyboard and multiple gamepads to the same
emulated input, and then just use whatever controller you want.
Because USB gamepad makers failed to provide unique serial#s with each
controller, we have to limit the mapping to specific USB ports.
Otherwise, we couldn't distinguish two otherwise identical gamepads. So
basically your computer USB ports act like real game console input port
numbers. Which is kind of neat, I guess.
And the really nice thing about the new system is that we now have the
capability to support hotplugging input devices. I haven't yet added
this to any drivers, but I'm definitely going to add it to udev for v094
official.
Finally, with the device ID (vendor ID + product ID) exposed, we gain
one last really cool feature that we may be able to develop more in the
future. Say we created a joypad.bml file to include with higan. In it,
we'd store the Xbox 360 controller, and pre-defined button mappings for
each emulated system. So if higan detects you have an Xbox 360
controller, you can just plug it in and use it. Even better, we can
clearly specify the difference between triggers and analog axes, and
name each individual input. So you'd see "Xbox 360 Gamepad #1: Left
Trigger" instead of higan v093's "JP0::Axis2.Hi"
Note: for right now, ethos' input manager isn't filtering the device IDs
to look pretty. So you're going to see a 64-bit hex value for a device
ID right now instead of something like Joypad#N for now.

Changelog:
- GBA: SOUND_CTL_H is readable, fixes sound effects in Mario&Luigi
Superstar Saga [Cydrak] (note: game is still unplayable due to other
bugs)
- phoenix/Windows: workaround for Win32 API ListView bug, fixes slot
loading behavior
- ruby: added udev driver for Linux with rumble support, and added
rumble support to existing RawInput driver for XInput and DirectInput
- ethos: added new "Rumble" mapping to GBA input assignment, use it to
tell higan which controller to rumble (clear it to disable rumble)
- GBA: Game Boy Player rumble is now fully emulated
- core: added new normalized raw-color palette mode for Display
Emulation shaders
The way rumble was added to ethos was somewhat hackish. The support
doesn't really exist in nall.
I need to redesign the entire input system, but that's not a change
I want to make so close to a release.

Updated to support latest phoenix changes.
Converted Settings and Tools to TabFrame views.
Errata:

Changelog:
- nall: fixed major memory leak in string class
- ruby: video shaders support #define-based settings now
- phoenix/GTK+: support > 256x256 icons for window / task bar / alt-tab
- sfc: remove random/ and config/, merge into system/
- ethos: delete higan.png (48x48), replace with higan512.png (512x512)
as new higan.png
- ethos: default gamma to 100% (no color adjustment)
- ethos: use "Video Shaders/Display Emulation/" instead of "Video
Shaders/Emulation/"
- use g++ instead of g++-4.7 (g++ -v must be >= 4.7)
- use -std=c++11 instead of -std=gnu++11
- applied a few patches from Debian upstream to make their packaging job
easier
So because colors are normalized in GLSL, I won't be able to offer video
shaders absolute color literals. We will have to perform basic color
conversion inside the core.
As such, the current plan is to create some sort of Emulator::Settings
interface. With that, I'll connect an option for color correction, which
will be on by default. For FC/SFC, that will mean gamma correction
(darker / stronger colors), and for GB/GBC/GBA, it will mean simulating
the weird brightness levels of the displays. I am undecided on whether
to use pea soup green for the GB or not. By not doing so, it'll be
easier for the display emulation shader to do it.

Changelog:
- added SA-1 MDR; fixes bug in SD Gundam G-Next where the main
battleship was unable to fire
- added out-of-the-box support for any BSD running Clang 3.3+ (FreeBSD
10+, notably)
- added new video shader, "Display Emulation", which changes the shader
based on the emulated system
- fixed the home button to go to your default library path
- phoenix: Windows port won't send onActivate unless an item is selected
(prevents crashing on pressing enter in file dialog)
- ruby: removed vec4 position from out Vertex {} (helps AMD cards)
- shaders: updated all shaders to use texture() instead of texture2D()
(helps AMD cards)
The "Display Emulation" option works like this: when selected, it tries
to load "<path>/Video Shaders/Emulation/<systemName>.shader/"; otherwise
it falls back to the blur shader. <path> is the usual (next to binary,
then in <config>/higan, then in /usr/share/higan, etc); and <systemName>
is "Famicom", "Super Famicom", "Game Boy", "Game Boy Color", "Game Boy
Advance"
To support BSD, I had to modify the $(platform) variable to
differentiate between Linux and BSD.
As such, the new $(platform) values are:
win -> windows
osx -> macosx
x -> linux or bsd
I am also checking uname -s instead of uname -a now. No reason to
potentially match the hostname to the wrong OS type.

Changelog:
- added Cocoa target: higan can now be compiled for OS X Lion
[Cydrak, byuu]
- SNES/accuracy profile hires color blending improvements - fixes
Marvelous text [AWJ]
- fixed a slight bug in SNES/SA-1 VBR support caused by a typo
- added support for multi-pass shaders that can load external textures
(requires OpenGL 3.2+)
- added game library path (used by ananke->Import Game) to
Settings->Advanced
- system profiles, shaders and cheats database can be stored in "all
users" shared folders now (eg /usr/share on Linux)
- all configuration files are in BML format now, instead of XML (much
easier to read and edit this way)
- main window supports drag-and-drop of game folders (but not game files
/ ZIP archives)
- audio buffer clears when entering a modal loop on Windows (prevents
audio repetition with DirectSound driver)
- a substantial amount of code clean-up (probably the biggest
refactoring to date)
One highly desired target for this release was to default to the optimal
drivers instead of the safest drivers, but because AMD drivers don't
seem to like my OpenGL 3.2 driver, I've decided to postpone that. AMD
has too big a market share. Hopefully with v093 officially released, we
can get some public input on what AMD doesn't like.
