Update to v094r15 release.

byuu says:

Implemented the cheat database dialog, and most of the cheat editor
dialog. I still have to handle loading and saving the cheats.bml file
for each game. I wanted to finish it today, but I burned out. It's a ton
of really annoying work to support cheat codes. There's also some issue
with the width calculation for the "code(s)" column in hiro/GTK.

Short-term:
- add input port changing support
- add other input types (mouse-based, etc)
- finish cheat codes

Long-term:
- add slotted cart loader (SGB, BSX, ST)
- add DIP switch selection window (NSS)
- add overscan masking
- add timing configuration (video/audio sync)

Not planned:
- video color adjustments (will allow emulated color vs raw color; but
  no more sliders)
- pixel shaders
- ananke integration (will need to make a command-line version to get my
  games in)
- fancy audio adjustment controls (resampler, latency, volume)
- input focus settings
- localization support (not enough users)
- window geometry memory
- anything else not in higan v094
