Created a splash screen state for loading resources.

Browse Source 
- Game now boots to splash screen, which displays parser progress.
- Added option "LoadVerbose" to disable rendering the progress text.
- Main Menu backgrounds now fade in regardless of DynamicBackground setting (as a transition from the splash screen).
