#35 AIM Background Colors for Webkit

[Nick Peshek]

This patch will allow you to use AIM background colors with
Webkit.
(This works on a per-theme basis right now)
I included an updated Mockie so that you can see how it works.
Feel free to do any changing of code that you want (As I am new at
Cocoa coding and probably made mistakes with my copy/pasting)
