Bug fixes (after the code jam)

Reacted to all your wonderful feedback and fixed (first update after the code jam):

• Fine-tuned resource balance.
• Fine-tuned building "work" speed.
• Made planets a bit bigger (and screen size independent).
• Made adaptive text contrast (it adjusts automatically to planet coloring).
• Fullscreen mode.
• Made game speed frame rate independent.
• Building position (now the buildings must stand on flat ground).
• You must build the restoration centers in Earth (instead of them already being there).
• "Planet sensitive" build menu.
• Fixed flunky collision detection while on planets.
• Fixed building interaction zones to be building wide.
• Fixed controls not reacting when "Caps Lock" is on.

Thanks everyone for the input!
