Still have to look at each page in detail, but they roughly work now.

The 'default' theme is to come back shortly.

Strips down the default theme to a very bare minimum, to allow better theming.

The next commits will move this theme to 'raw', and commit a new default theme that looks mostly like the old one.

Renamed setup_groups to a more descriptive name.

Took away the check that means group owners can't leave groups for a bit. The implementation of this will need revisiting.

* A more neutral colour scheme, appropriate for a default installation
* Forms are layed out with the title beside the inputs
* The profile page is in tabs
* Layout is cleaner and clearer
* Still will be some bugs, especially in IE!

add better messages for when there are no groups to display
