started improving importer
worked at importing cameras
importer stuff 2.0
Merge branch 'importer' of https://github.com/GuidoSchmidt/EZRWS1314 into importer

Conflicts:
	src/utils/Importer.cpp
camera movement works dae-file cameras do not work
To use cameras, manually create a scene::Camera object, dae file import is
wrong, maybe blender export does not work?!
changed scene names for blend and dae files
load the correct dae file
added scene folder to resources
fixed some naming errors
merged renderer to master
