* Add an initial complete frame timeout to the WebSocket processor to make it easier to write WebSocket service code that is resistant to Denial of Service attacks.
* 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.
