LevelRenderer1_1 is not more, there is now only one LevelRenderer.
Ready to start working on the two levels in-between 1_1 and 1_4 (cave).
The cave level still needs to have enemies, but enemies are spawning in level 1_1 like before.

known issues:
	->HUD jumps when Rip starts to move.
	->Rip jumps slightly jumps when time stops.
	->the cave level background needs work.
