Accuracy: update accuracy docs with all known game bugs

[rawr51919]

Some of these may still need fleshed out with extra details, however this is already a good improvement for checking accuracy of emulated games

• Final Fantasy VI (HQ audio patch) (bugged audio: Final Fantasy VI Advance [Restored] audio is bugged with the MP2K HLE option. #180) (minor issue)
• WarioWare - Twisted! (requires gyro sensor emulation: WarioWare - Twisted! (USA) low fps #103)

These aren't accuracy issues.

• The HQ audio patch simply is incompatible with the HQ audio mixer feature in NBA. This is because of modifications the patch makes to the original audio engine.
• WarioWare - Twisted! is a case of peripheral hardware that currently is unsupported

• Final Fantasy VI (crashes at random: Final Fantasy VI crashes at random interval with NanoBoyAdvance #220)

I haven't been able to reproduce this issue at all yet and it's questionable whether it still exists, if that bug really exists.

• All Inside-cap visual novel ports (emulator detection gets set off: [Emulator detection] Inside-cap visual novel ports #203)

This is a fair addition. If you remove the other three additions, I will merge this.

Did those tweaks as requested.
