updates

This is a pull request around these commits:
https://github.com/dportabella/biemond-orawls-vagrant/commits/dev

I guess that it's easier to integrate these changes if coming from a fork of biemond-orawls instead of biemond-orawls-vagrant.
please let me know which, if any, of these commits you are interested in,
and I will add them in fork of biemond-orawls.
