ServerEnvironment & StaticObject cleanups

Browse Source 
* isFreeServerActiveObjectId is now part of ServerEnvironment
* getFreeServerActiveObjectId is now part of ServerEnvironment
* StaticObject constructor now take ServerActiveObject instead of type + string. This permits to remove a big string copy in some code parts
