Mostly everything is implemented already; only graphics and minor tweaks
are required at this point.

Some notable tweaks to the SL base theme:
-the step artist will now center itself when no machine/personal record
is made
-SL theme uses the bottom bar on ScreenSelectMusic, which will house
profiles in a later version
-SL theme has user-configurable location strings for screenshot screens
-added SIMfile folder on ScreenSelectMusic
