Update to v082r26 release.

byuu says:

.cht files now use BML-formatted data. I'm still going to request the
cheats.xml file as-is, and will write my own converter for embedding
during releases.
This is where parsing 2MB markup files in 10ms is really going to be
nice. Had to use an evil hack before for actually searching for games.

This has the start of the board/chip separation from mappers for NES,
and it has a barebones iNES->board markup converter.
You can specify your own board markup and bypass the need for an iNES
header, so in other words it will load No-Intro style games with
a proper board file.
Long-term, we'll have an internal database for commercial boards, and
probably folder.fc/prg.rom{,chr.rom} loading support.

Since they can't co-exist, the mappers are currently disabled, and I've
only ported the easy ones. So no MMC1/MMC3/VRC6 in this release. I need
to make them into chips first.
