#35 Edit Transition Delay

Precalculate KGNoise color for cell background.
Saves every cell from having to recalculate it upon rendering.
This speeds up the time for the Edit transition.

#53 Nav Bar Icon Color

Changes color of navigation bar items to blend in with bar.
Looks a lot cleaner not having button colors jump out at you,
especially with already having 4 buttons in the nav bar.
