- added: classic and nunchuk support
- added: all controllers can now be configured
- added: GC version (untested)
- changed: mappings are no longer stored in SRAM, but in config file.
This means no per-game configurations, but one global
config per controller.
- one makefile to make all versions. (thanks to snes9x143 SVN)
