Document the process of making this plugin

[AObuchow]

On Twitter, @davidsalter asked if I could do a write-up about how this plugin was made.

To quote him:
"I was thinking from a development point of view. For example, how did you create the project, what code do you need to write to change the theme etc. I’d certainly be interested in the technical details."

Some of the contents of this write-up could include:

• Why I started this plugin
• Resources I used to make the plugin (Primarily @vogella tutorials & looking through Eclipse source code)
• The typical development workflow (using color-pickers & referencing the Eclipse Platform theme's CSS)
