* Fix for r60163: in RC/RCL, hash together all the options, not just namespace, in order to form the cache key.
* Removed Crb from the credits since none of his code remains.
* Fixed two bugs which both broke feed links on RCL: $this->mTargetTitle not initialised when setTopText() is called, and $out->setFeedAppendQuery() in setBottomText() overridden by a subsequent call to setSyndicated(). Fixed both by rearranging data flow, using memoized accessors instead of setup functions to eliminate bugs due to execution order.
* Renamed a few variables which were unclear ($feed and $feedObj).
