Fixed a query for tasks (not displaying things correctly). Removed the code for deletion of the is_observer_p flag as it did not make much sense. Changed the behaviour of 'Pool Tasks' so they display all tasks where I'm participating. Mark all tasks where I'm not an observer with a green title
Made sure the projects portlet only shows projects you have a role in, unless you are in a community. Little bit of performacne tuning on the tasks portlet
