Visuals and options!

Overall visual update to make the stage visually clearer and visual updates to the attacks to make them look more fluid and better.

Music options in the main menu (press left or right on the start game screen) now let you switch between the default music, AI music and muted music!

While NOT in combat players can now return to the main menu to change audio settings by pressing "Start"  or "ENTER/RETURN". This will not reset the death counter.

Other minor bug fixes.
