Demo update and start counting tests times

-Fixed performance issue with multithreading and rendering
-start making better shaders (by using many macros)
-speed up rendeing when maximum objects count was reached
-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)
-starts adding multithreaded rendering
-added some math to vectors
-changes execute() to willExecute(). Probably should have different name.
