[GP2X / WIZ] Picodrive v1.80

[*]Added Caanoo support. Now the GP2X binary supports GP2X F100/F200, Wiz
and Caanoo. Lots of internal refactoring to support this.
[*]Enabled 32X and SMS code. It's still unfinished but better release something
now than wait even more (it has been in development for more then a year now
due to various other projects or simply lack of time).
[*]GP2X: Added basic line-doubling vertical scaling option.
[*]Changed the way keys are bound, no need to unbind old one any more.
[*]Handle MP3s with ID3 tags better (some MP3s with ID3 did not play).
[*]Improved shadow/hilight color levels.
[*]Fixed broken cheat support.
[*]Internal refactoring for 32x/SMS support.
[*]Move mapper database to external file.
[*]Added preliminary SMS emulation.
[*]Added emulation of 32x peripherals including VDP. More work is needed here.
[*]ARM: Added new SH2 recompiler for 32x. Some unification with SVP one.
