An extra ".citra-emu.org," was left when the link was changed to the current forum URL, so I fixed that.

The Citra forum (discuss.citra-emu.org) has recently been down. The link that has been added 
in this file now leads to an error pages. I update updated the link so it now leads to Citra's new
forum.

I believe putting comments in the headers has won by a good margin, with everyone other than me preferring it, so time to enshrine it.

Closes #215

- removed variable naming starting with "_"
- removed "Always break, even after a return" from case statements
