Servlet to upgrade connections to WebSocket

The request must have the correct upgrade headers, else it is handled as a normal servlet request.

The initParameter "bufferSize" can be used to set the buffer size, which is also the max frame byte size (default 8192).

The initParameter "maxIdleTime" can be used to set the time in ms that a websocket may be idle before closing (default 300,000).
