Buildout

To help with development in an controlled environment buildout helps at some point. Even if the same can be achieved with naked virtualenv -  buildout makes i more explicit and documented. This is purely optional. 

Remark:
I put this on the main branch maintain/0.6.x - however theres also master and develop. This is quite confusing and there should be a statement somewhere whats the proposed process for development is, esp. which branch to fork. I hope I took the righ one.
