Update to v093r13 release.

byuu says:

This WIP removes nall/input.hpp entirely, and implements the new
universal cheat format for FC/SFC/GB/GBC/SGB.

GBA is going to be tricky since there's some consternation around
byte/word/dword overrides.

It's also not immediately obvious to me how to implement the code search
in logarithmic time, due to the optional compare value.

Lastly, the cheat values inside cheats.bml seem to be broken for the
SFC. Likely there's a bug somewhere in the conversion process. Obviously
I'll have to fix that before v094.

I received no feedback on the universal cheat format. If nobody adds
anything before v094, then I don't want to hear any complaining about
the formatting :P
