-added some new types to gui manager + some fixes
-TexCoordsManager now working (probably)
-added CRenderDefault components which makes entities without texcoords possible to draw
-makes better way of binding demos to launcher
-moved some registration related to rendering to one function (basic components + draw system)
-added Sandbox demo (demo which takes all demos to one demo)
-extends ParticlesDemo play area
-added BirckBreaker demo (WIP)
-added special material to additive particles
-added whole bunch of rendering code to rendering module
-added ability to show filtered entities (blinking)
