userExits evt.userId is not number

[Virusescu]

When handling userExits internal event, one would expect the evt.userId to be a number but it is a java.lang.String - I think
This could bother you when trying to get the user object that just quit the room.
Using _server.getUserById(evt.userId) would yeld this error

org.mozilla.javascript.EvaluatorException: Can't find method it.gotoandplay.smar
tfoxserver.SmartFoxServer.getUserById(java.lang.String). (thu_challenge.as#255)

However... if used like _server.getUserById(Number(evt.userId)) it works ok...

Thanks for spotting it,
we'll add this fix in the next release.
