MyObjects Release Candidate 1 Released

This release should be stable enough for production. The api will not be changed from this point.

Changes
* normalizedGet() method that generates cross table sql queries for retreiving the foreign objects and the requested object in a single query was redesigned. It now supports multiple foreign keys pointing to a single table.
* Class property names that are holding foreign object instances can now be overridden in the web gui.
* Some little bugs were fixed and the urls pointing to old web site were changed to www.myobjects.org
