Portlets relocated in New svn

Portlets relocated in New svn

The following svn changes were made to move all incubating portlets to the portlets svn directory and move all non-incubating portlets into the svn sandbox.  Future new portlets should be started in sandbox and can be moved to portlets/ during incubation.

SimpleContentManagement portlet has been submitted for incubation and will be accepted at June meeting of the incubation committee. Until then it resides in portlets/.
