Added (not fully functioning) qunit test

Ajax-test works if OnlineUserList runs. Which it seldom does.

I can't seem to get testOnlineUserList to run. It complains about a
undefined method. Don't really know what to do and it's difficult to
test because OnlineUserList doesn't work as often as i wish it would.
Rage commit
QUnit test works!

Check testOnlineUserList for test-case.
Test passed if database contains 2 online users.
