Projector V

* Changed wording: element is one element on the projector. A slide is a functoin to render one element
* Use AllData as first argument all the time
* Render username on server
* Add exceptions for erros on projector
* Fix motion recommendation
* Only show state extension, if it is allowed by the state
* Add motion_change_recommendations to motion full_data
