Added newest Ghoul version

added call to updateCamera for current focus node. (Note that this causes master to be 1 frame ahead of slaves and should be changed)

It is so far empty but will be used later on for initialization

Created own shaders for RenderableSphere

Conflicts:
	src/engine/openspaceengine.cpp

added a boolean _timeJumped which is synced and set to true whenever setTime is called.
(Note this is never set to false afterwards unless a call is made to setTimeJumped( bool ) with value false)
