Update to v093 release. 

byuu says:

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.

//nall::property implements ownership semantics into container classes
//example: property<owner>::readonly<type> implies that only owner has full
//access to type; and all other code has readonly access.
//
//property can be used either of two ways:
//struct foo {
// property<foo>::readonly<bool> x;
// property<foo>::readwrite<int> y;
//};
//-or-
//struct foo : property<foo> {
// readonly<bool> x;
// readwrite<int> y;
//};
//return types are const T& (byref) instead of T (byval) to avoid major speed
//penalties for objects with expensive copy constructors
//operator-> provides access to underlying object type:
//readonly<Object> foo;
//foo->bar();
//... will call Object::bar();
//operator='s reference is constant so as to avoid leaking a reference handle
//that could bypass access restrictions
//both constant and non-constant operators are provided, though it may be
//necessary to cast first, for instance:
//struct foo : property<foo> { readonly<int> bar; } object;
//int main() { int value = const_cast<const foo&>(object); }
//writeonly is useful for objects that have non-const reads, but const writes.
//however, to avoid leaking handles, the interface is very restricted. the only
//way to write is via operator=, which requires conversion via eg copy
//constructor. example:
//struct foo {
// foo(bool value) { ... }
//};
//writeonly<foo> bar;
