[Bf-docboard] Force Fields and Collisions

[Tobias Regenbrecht]

I have updated the page about Force Fields and Collisions (split them in two), 
Jahka was so kind and clear the rest of items I did not know.

Maybe someone would be so kind and revise the pages? Since I have written them 
with the current SVN version I have used version number 2.49. When it will be 
officially released we can move them into the manual.

With kind regards
