This WIP is just work on nall/primitives ...
Basically, I'm coming to the conclusion that it's just not practical to
try and make Natural/Integer implicitly castable to primitive signed and
unsigned integers. C++ just has too many edge cases there.
I also want to get away from the problem of C++ deciding that all math
operations return 32-bit values, unless one of the parameters is 64-bit,
in which case you get a 64-bit value. You know, so things like
array[-1] won't end up accessing the 4 billionth element of the array.
It's nice to be fancy and minimally size operations (eg 32-bit+32-bit =
33-bit), but it's just too unintuitive. I think all
Natural<X>+Natural<Y> expessions should result in a Natural<64> (eg
natural) type.
nall/primitives/operators.hpp has been removed, and new
Natural<>Natural / Integer<>Integer casts exist. My feeling is that
signed and unsigned types should not be implicitly convertible where
data loss can occur. In the future, I think an integer8*natural8 is
fine to return an integer64, and the bitwise operators are probably all
fine between the two types. I could probably add
(Integer,Natural)+Boolean conversions as well.
To simplify expressions, there are new user-defined literals for _b
(boolean), _n (natural), _i (integer), _r (real), _n# (eg _n8),
_i# (eg _i8), _r# (eg _r32), and _s (nall::string).
In the long-term, my intention is to make the conversion and cast
constructors explicit for primitive types, but obviously that'll shatter
most of higan, so for now that won't be the case.
Something I can do in the future is allow implicit conversion and
casting to (u)int64_t. That may be a nice balance.

Changelog:
- added \~130 new PAL games to icarus (courtesy of Smarthuman
and aquaman)
- added all three Korean-localized games to icarus
- sfc: removed SuperDisc emulation (it was going nowhere)
- sfc: fixed MSU1 regression where the play/repeat flags were not
being cleared on track select
- nall: cryptography support added; will be used to sign future
databases (validation will always be optional)
- minor shims to fix compilation issues due to nall changes
The real magic is that we now have 25-30% of the PAL SNES library in
icarus!
Signing will be tricky. Obviously if I put the public key inside the
higan archive, then all anyone has to do is change that public key for
their own releases. And if you download from my site (which is now over
HTTPS), then you don't need the signing to verify integrity. I may just
put the public key on my site on my site and leave it at that, we'll
see.

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.
