Subject: [PATCH] * Added a unique and interesting WebSocket grid login
 processor by hijacking the LLSD login code.    This sends the data through
 the normal login channels and spits out a JSON object back that mimics the
 login response.    Feel free to comment on the best way to set this up as a
 config option.
