New theme creation

Once you have chosen the theme name, a directory with the same name will be created in the "theme" directory of your Ubooquity working directory.
It contains all the default theme files. Your theme is now ready to be edited. Modify these files as you like to change the way Ubooquity pages look.

To see your modifications, select your new theme in the "General" settings section and restart the server.
Don't forget to force the refresh of the page after each modification to bypass the cache of your browser (Shift + F5 in most browsers).
