Update to v092 release.

In the release thread, byuu says:

    The first official release of higan has been posted. higan is the
    new name for bsnes, and it continues with the latter's version
    numbering.

    Note that as of now, bsnes still exists. It's a module distributed
    inside of higan. bsnes is now specific to my SNES emulator.

    Due to last minute changes to the emulator interface, and missing
    support in ananke, I wasn't able to include Cydrak's Nintendo DS
    emulator dasShiny in this build, but I hope to do so in the next
    release.

    http://code.google.com/p/higan/downloads/list

    For both new and experienced users, please read the higan user guide
    first:

    http://byuu.org/higan/user-guide

In the v091 WIP thread, byuu says:

    r15->r16:
    - BS-X MaskROM handling (partial ... need to split bsx/flash away
      from sfc/chip, restructure code - it requires tagging the base
      cart markup for now, but it needs to parse the slotted cart
      markup)
    - phoenixflags / phoenixlink += -m32
    - nall/sort stability
    - if(input.poll(scancode[activeScancode]) == false) return;
    - MSU1 / USART need to use interface->path(1)
    - MSU1 needs to use Markup::Document, not XML::Document
    - case-insensitive folder listings
    - remove nall/emulation/system.hpp files (move to ananke)
    - remove rom/ram id= checks with indexing
    X have cores ask for manifest.bml (skipped for v092's release, too
      big a change)
    - rename compatibility profile to balanced (so people don't assume
      it has better compatibility than accuracy)

+//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.
+//
+//this code relies on extended friend semantics from C++0x to work, as it
+//declares a friend class via a template paramter. it also exploits a bug in
+//G++ 4.x to work even in C++98 mode.
+//
+//if compiling elsewhere, simply remove the friend class and private semantics
+
+//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:
