There is no request parameter name set, so forwarding will fail. Fixed
by this patch.

There is one major bug in websocket implementaton crashing the
application on websocket disconnect caused by NullPointerException.

It seems that disconnect is done after some dependencies are closed.
This might be caused by data serialisiation.

This could be used to send data via websockets without searching
sessionIDs or user tables within ARSnova.

Simply publish an event with ARSnova-sessionKey from within the
application.

This sets current user and ARSnova session information in a session
scoped service bean. If the user connects with a websocket, the
websocket session ID will be set in addition to the user and session
object.

The aspects methods pointcut after returning from joinSession() method
in SessionService. So the UserSessionService will be set with all needed
data after a user successfully joins a session.

With this service available, it can be used to replace some usage of
Array/Map based application wide data structures that cause some trouble
when stopping or redeploying the application.

Use service and dao beans in application context and controllers in
servlet context. This prevents controller beans from being created twice
in application and servlet context witch causes some trouble in the
past.

This bean will now be linked to a session returning different values for
different sessions and users.
It can be used to access current users (ARSnova)-session and user object.

This bean holds user and session object of the current user after he
joins a session and could be used to access those objects within the
application.

Added two simple URIs to get a JSON representation of the referenced
objects.

Jenkins tries to use old version 2.1.1 but this artifact is not
available anymore.

This indicates conflicts in CouchDB that should be handled by
application. Those conflicts might occure, if a single user is logged in
on two different devices at the same time.

Those logging entries are obsolete and only used to grow log files ;-)
Only log log entries if an error occured - not for each event.

These classes could be used to replace methods from DAO class.
