#24 Texture Atlas : Vertex Generation WIP

- made TextureAtlasRenderer a RenderPass
- WIP on TextureAtlasVertexGenerator
- reading the texture works
- no idea whether those vertices are correct, though
Hotfix : SubjectListenerPattern detaching Listeners

- can now be called form within a Listener
#26 Manipulating Values :  added Utility Listeners

- added some generic Listeners which might come in handy later
- UNTESTED, though
