Update to v096r01 release.

byuu says:

Changelog:

- restructured the project and removed a whole bunch of old/dead
  directives from higan/GNUmakefile
- huge amounts of work on hiro/cocoa (compiles but ~70% of the
  functionality is commented out)
- fixed a masking error in my ARM CPU disassembler [Lioncash]
- SFC: decided to change board cic=(411,413) back to board
  region=(ntsc,pal) ... the former was too obtuse

If you rename Boolean (it's a problem with an include from ruby, not
from hiro) and disable all the ruby drivers, you can compile an
OS X binary, but obviously it's not going to do anything.

It's a boring WIP, I just wanted to push out the project structure
change now at the start of this WIP cycle.
