Cleanup of TODOs
Some TODO changes
Formatting as I read code
Some cleanup, fader is unused in orb
Renaming level files
Added a pause mechanism in XML

adding pause="true" to a step tag now triggers an auto pause this
provides a simple mechanism for pausing after coop sessions for example
Added text for all levels in LevelSelect HUD

All song names can now be seen in level select HUD for clarity and ease
of selection
Added pause after all coop->versus transitions
A number of small changes

-Saturation cap for BG color is now in LEVEL_CONSTANTS and set to 0.65
-Mouse click can be used to pause, may be useful for remote triggering
-Added 'dingding' sound when unpausing prox level and when leaving
transistions to evoke the start of the round
-Changed default buffer size so that samples like 'dingding' would
trigger faster
Added a jump to machanism for skipping

-Prox level now supports pressing 's' to skip to the next transistion
-Trying to work out the kinks of the dingding and other audio buffering
-Adjusting tau/saturation for bg some more
Added an adjustement mode to scale the screen
Added Serializer and added serialization for scaling

Scaling gets saved in a serialized filed
Little cleanup
Added a preview mechanism for song

Songs can be listened to in the main menu to preview them
Added BPM display in LevelSelect
Fixed a bug which may be the root of the no audio issue
