Made the cloning aware of Open Atrium, including:

 * Space and section heirarchy.
 * Difference between Space and Group.
 * Colorizer settings.
 * OG variables.
 * OG roles and permissions.

Also, adds "jump links" so you can quickly create Spaces/Sections of a particular type and easily 'Create a Space Type from this Space'.
