Subject: Adds ips/bps softpatching

Patches named like the content will be auto-applied in memory when the
game is loaded.

Example: /roms/game.gba will apply patches named /roms/game.ips,
/roms/game.ips1, /roms/game.IPS2, /roms/game.bps, etc. This only
happens in memory, original files are unmodified.

Patches are loaded in case-insensitive alphabetical order. Note that
.ips12 loads before .ips2, but after .ips02.

Only supports cores that load from memory (see libretro page at
https://docs.libretro.com/guides/softpatching/ for compatibility list)
