Some code cleanup.
Fix TextureInfo::FromPicaRegister.
video_core: Add documentation on the DebugContext interface.
More coding style fixes.
citra-qt: Rename "Stop Tracing" to "Finish Tracing".

This better reflects that no commands are supposed to show up until you hit the button a second time.
Pica: Re-enable command names on MSVC.

The affected code is no longer limited by compiler support on that platform.
More cleanups.

fixup! Fix one major bug and one little annoyance in CSpinBox
