Configure access policies for WHOFIC editors

[tudorache]

For the release, regular editors should not be able to delete classes. And possibly other operations will be banned.

this is partially fixed

I need to figure out why the button is just being disabled instead of hiding it.

Actually i realised this is not implemented correctly. In this current implementation the application does not chare if you have that role on a specific project as long if you have that role. This needs to be reimplemented so that we check both the project and the role you have assigned on that project.
