[Suggestion] Rename 'OpenTyrian2000' Menu option to 'Setup'

[OpenRift412]

This is probably just an OCD thing, but it just seems a little weird to have the OpenTyrian-specific settings just labelled as 'OpenTyrian2000' instead of something more informative like 'Settings' or 'Setup'. In my opinion it gives the impression that it's more of just an about screen than a menu with additional settings.

Thoughts?

I'm not sure I actually agree with this, as "Setup" doesn't really indicate that options specifically related to OpenTyrian2000 are to be found there. "OT2K Setup" may be better.

Well the jukebox is also located there, so I think a more agnostic name would still be appropriate.
