SM.Core:
+ Particle System
+ scriptable system for scripts

~ Moved Texts- and Particles-namespace to SM.Base.Drawing
~ Changed how you tell the stopwatch to pause. (From method to property)
~ Fixed Randomize.GetFloat(min, max)
~ Now automaticly adds the DrawingBase.Transformation to DrawContext.ModelMatrix. No need to change DrawContext.Instances[0], anymore.

SM.OGL:
+ "one-file-shader"-support

SM2D:
+ DrawParticles (Control for Texture and Color not there yet)

~ Changed coordnate system to upper-right as (1,1)
~ Changed default shader to "one-file-shader"
