SugarForge/SugarExchange rating & review feature

[ftreml]

The existing rating & review feature for sugarforge/sugarexchange projects should result in "most rated", "top rated" etc listings.
For members of a project it should be not possible to rate own projects - seemed to happen here: http://www.sugarforge.org/reviews/?group_id=245

Autsch! Seems that "recruiter01" is very gentle in reviewing his own product... really funny!
