Animate moving between games

Use cinder timeline and anim classes to move camera to get a smooth
animated transition between games.
Updated background rendering, fix resize issues, fix framerate issues.

* Render a gigantic sphere that the scene is inside and light it to get a cool gradient background effect. I had to modify the phong shader to accept a color to get this to work. Should probably look into passing along vertex attributes or something for coloring like a real opengl program but works for now...

* Resize Fbo's when the screen resizes so rendering doesn't get screwed up when starting a game

* Fix unusual framerate issues after returning from MAME by setting 0 as the multisampling arg passed to CINDER_APP_BASIC macro.

* Retab files using spaces instead of tabs.
