-remove map rendering form Snake demo, and render entities by themself
-start adding depth and color rendering parameters
-added properly names to jobs (for debugging purpses)

-fixed bug with high CPU usage (use pthread instead of builtin D multithreading)
-added new graphics
-snake now render tile coresponding to body part
-snake is destroyed after collision and emit some particles
-added some functionality to vectors
-fixed documentation issue in Manager.d
-fixed bug in EntityManager
