Post-SOC color.module #2 - Batch API, Enable/Disable on a per-theme basis

Commit #136009

After color.module is enabled -- users will have the optional to generate schemes + enable the schemes if they're available for the theme.

  - Demonstration theme are being tweaked to look more presentable as colorable themes :)
  - Updated caching to include "Page compression"
  - New feature for theme developers, when scheme editing there will be a textfield where devs can have the color.inc code for a scheme to copy and paste right in! Yay! It was simple to do and helpful :)
  - Updated Nista theme. Updated its schemes. Very nice progress.
  - Updated Spooner, Cleanstate for text-decoration: none on anchors
  - Textarea resized for color.inc viewer
  - Color admin re-factored to conserve space.
  - (Big improvement) Batch API generation and installer
  - (System services) Color.module will only attach after it's activated for a theme, or else it will fall back to the default.
  - Color scheme config panel, admin/settings/schemes
  - More work is being done to slim the system down and make it more modular.
