- fix some issues with the SimpleOpenGl sample: 

* Material's shininess would not be set if strength wasn't defined too;
 * Two-sided culling was working the opposite way, GL_CULL_FACE actually removes back faces when enabled;
 * GL_COLOR_MATERIAL should not be enabled for mesh->mColors since it replaces other materials, it now sets vertex color only. Also, it now uses glColor4fv directly. 
Thanks to Ricardo Costa for the patch (http://sourceforge.net/projects/assimp/forums/forum/817653/topic/4502991).
- some doc and formatting fixes in the very same sample.
