added goolf easyconfigs (+ sync with develop)

@stdweird: This basically only adds `goolf` equivalents for the `goalf` easyconfigs. 

I tested all easyconfigs (`ictce`, `goalf` and `goolf`), all working fine, so I'd like to merge in https://github.com/hpcugent/easybuild-easyconfigs/pull/131 with this included.
