7d - adapting (My)Action Spaces menu from " Groups" menu

this menu is in navigation for logged in participants ( when they are not logged in) the (My)disappears and the capacity to edit my action space

A- Modify Action space (instead of Groups) (opening 2 tabs : My Action spaces, All action spaces)
-when clicking on this menu , we get the List of Action spaces by Title, with the following columns
 Manager,
 numberof Participants (Subscribers)( when clicking there one access their list with their permission) ,
 title of the “first action” in that action space (the sticky one) ( this replace the group description which is cancelled
 number of posts during the last week ? or last update ( some indication of the group activity)
(? number of administrators - if useful later on)

B-Vocabulary : Instead of “subscribe”, put “Join”.

C-The first column of groups now brown should be same color as rest.

D-consider if creating a third tab "Find an action space " (along the tags of its "first action " ), like "Find an action" makes sense - may be not , may be the current title search is enough

E- See about the current bug in the search : "dress" is not found, while "Dress " finds groups with "dress" in their name
