Improved consistency for new visualization system. Colors were not rendered otherwise.
btw. this part of the code was not executed anyway if a .ces file was parsed.
IMPORTANT. The ChParticleEmitter has been removed from the source directory because now it is officially part of Chrono::Engine.
You can find the same functionality by linking the header in chrono source directory, in detail  particlefactory/ChParticleEmitter.h
To this end, you MUST pull the latest chrono repository from the GIT! (the development branch) - this done , all should work exactly as before.
