options interface for chrome - first draft

I have updated the options interface with the following:
1. Add style to interface through external style sheet.
2. Create a radio button selection for the user to choose between on and off states for the content server.
3. If the user chooses the on state then display a hidden sub-menu of radio buttons that the user can choose from. These consist of three predefined selections or the 'other' selection that allows the user to enter their own content server.
4. If the the predefined selections are chosen, automatically save choice to local storage.
5. If the user enters their own content server, validate this server by making a request to the server and checking for a response or error. Inform the user of success or failure. Obviously a connection to the Internet must be present.
6. Saving the server to local storage by the use of a button, informing the user of success or failure.
