Lots more timing improvements to GBA emulation. We're now ahead of
everything but mGBA.
Mario & Luigi is still hanging in battles, so I guess my prefetch
simulation isn't as good as Cydrak's previous attempt, no surprise.

This WIP scores 448/920 tests passed.
Gave a shot at ROM prefetch that failed miserably (ranged from 409 to
494 tests passed. Nowhere near where it would be if it were implemented
correctly.)
Three remaining issues:
- ROM prefetch
- DMA timing
- timers (I suspect it's a 3-clock delay in starting, not a 3-clock into
the future affair)
Probably only going to be able to get the timers working without heroic
amounts of effort.
MUL timing is fixed to use idle cycles.
STMIA is fixed to set sequential at the right moments.
DMA priority support is added, so DMA 0 can interrupt DMA 1 mid-transfer.
In other news ...
I'm calling gtk_widget_destroy on the GtkWindow now, so hopefully those
Window_configure issues go away.
I realize I was leaking Display* handles in the X-video driver while
I was looking at it, so I fixed those.
I added DT_NOPREFIX so the Windows ListView will show & characters
correctly now.

Changelog:
- Game Boy (Color): STAT OAM+HBlank IRQs only trigger during LY=0-143
with display enabled
- fixes backgrounds and text in Wacky Races
- Game Boy (Color): fixed underflow in window clamping
- fixes Wacky Races, Prehistorik Man, Alleyway, etc
- Game Boy (Color): LCD OAM DMA was running too slow
- fixes Shin Megami Tensei - Devichil - Kuro no Sho
- Game Boy Advance: removed built-in frame blending; display emulation
shaders will handle this going forward
- Game Boy Advance: added Game Boy Player emulation
- currently the screen is tinted red during rumble, no actual gamepad
rumble support yet
- this is going to be slow, as we have to hash the frame to detect the
GBP logo, it'll be optional later on
- Emulator::Interface::Palette can now output a raw palette (for Display
Emulation shaders only)
- color channels are not yet split up, it's just the raw packed value

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.
