* This commit incorporates the heart of the OpenGridProtocol patch that is currently on Forge in a nice, friendly modular format.

* There are a lot of changes and this is quite experimental.  It's off by default, but you can turn it on by examining the bottom of the opensim.ini.example for the proper OpenSim.ini settings.    Remember, you still need an agent domain..  
* Furthermore, it isn't quite right when it comes to teleporting to remote regions (place_avatar)
