Files temporarily renamed.

Skybox is loaded in preview rooms now via script
poster position in mediaroom was fixed
Reoccuring error: Monobehaviours in WebCommunication are not recognized anymore by unity

- weather change is received when it is changed via the website
- try to send the changes made in Unity [wip]
- unnecessary package removed from Weather (now correctly part of TeachR.Atmosphere)

- added script to websocketPrefab
- send information about available controllers to website
- receive a website request for new informations about the controller status

new class to drag and drop desired controller containing gameobjects

- removed outdated debug messages
- send function names to server
- receive availability status from server

Tested Scenes:
chemistry room
cs1 room
cs2 room
EntranceHall
fishBoneScene
frontalLectureScene
groupWorkScene
horseshoeRoom
MediaRoom

- added Monobehavior to websocket prefab and registered static init and eventloop of rtc coach on that script

expected result: websocket scripts will only be used if the websocket prefab is within the scene

# Conflicts:

OnUpdate, OnFixedUpdate and OnLateUpdate are now part of InitGlobals

cleaned up namespaces:
-  Name space = Package name
(except Replay)

- TeachR.RTC -> TeachR.WebCommunication
- TeachR.RTC.Editor -> TeachR.WebCommunication.Editor

fix merges, update unity to beta,

We add a system to allow our CoachRTC to run code in the standard logic.
This commit also adds some hotfixes to make parts of the classroom logic
more consistent in the RWTH version of the codebase.
In the future this should be fixed by providing solid, consistent access controls
for various resources, such as student slots and behavior controllers.
