Kokua:Release Notes/Kokua Release NORLV/5.1.6.43613

This release brings Kokua to parity with LL's 5.1.6 release http://wiki.secondlife.com/wiki/Release_Notes/Second_Life_Release/5.1.6.516459 along with a few minor bug fixes.

Thanks to Nicky for doing what proved to be a particularly complex merge since it coincided with my vacation.
