Comment 13 for bug 110108

I think this is the required UI changes to support the basic use case
    * Update TeamAddMyTeamsView.candicate_teams to return a tuple of
      admined teams and bool membership status.
    * Update setup fields and widgets to set the correct state
    * Update the action to process the removed teams
    * Update the link to the page to be add/remove my teams

I would like to see the +members and +participation pages to have an ajax dialog that lets me remove my teams.
