need working session management

[inf9144]

we need working session management to test features that are logon specific and build backend

[alexbiehl]

Use like this:

@Inject UserComponent userComponent;

....

User user = userComponent.getUser()
...

The user object is session scoped so you can store individual information on the user without conflicting any other active users.
