Added firehouse (red) theme

This adds a red theme.  I think some additional thought/work is needed to make creating theme's easier.  For example there are css classes like 'button-blue' but the themer may want to make the buttons a different color and there seems to be no way to do this other than assigning a non-blue color to class like 'button-blue' in the css.  This pull request doesn't solve that issue but does provide a usable red theme.
