[9:00][Find out if it worked]
[9:30][Resume work on RenderGroup structure, implementing Clear]
[10:47][Make DrawRectangle take A which defaults to 1.0f]

Cinera 0.7.0 Update Add output parameter to all of hero/code, hero/intro-to-c and hero/misc, preserving the current URLs while allowing different .hmml filenames, notably for hero/misc which now gets sorted chronologically.
