Minor performance improvement. Not sure why this was done but it's not required any more.
This is important when using dynamic compiling to rapidly iterate. Until we actually split projects out into pieces (like the abstract ruleset project we have talked about) there is no advantage to using internal in the osu! game code.
Also sets better defaults.
There should only ever be one osu! logo. It is now passed around between screens in a superfluous manner.
