Completed Gridster integration with saving position and sizes to the database.
Added a Note Dashlet that utilizes Markdown.js for formatting.
Added customization for background and font colors for individual dashlets.
Updated dashboard footer so the button is a whole button (it looks nicer).

Currently this implementation utilizes HTML5 color input, however there is support for a jQuery color picker which is contained and bundled on another branch.
Removed a redundant method from the Dashlet_Controller's $allowed_actions
Forgot that HTML5 automatically adds in # infront of colors as I was originally using a jQuery plugin.
Merge pull request #1 from Neumes/master
