[Bf-docboard] Material Preview page has been edited

[Olivier Saraja]

Hey all,

after writing my french Blender book and after a little rest, I'm back at the 
editing task of the wiki documentation. Nice job has been done here and 
there: congratulations, everybody!

I started with something easy, as I needed to get familiar again with Wiki 
editing (with which I never have been skilled anyway). So I updated the 
Material Preview page:

http://mediawiki.blender.org/index.php/Manual/Material_Preview

Could somebody be kind enough to redo and add the other preview screenshots? 
Spellchecking is also welcomed, of course.

Furthermore, for the next few evenings, is there any page you noticed that 
should need some slight update?

Cheers,
