Easier to set up permissions for projects

We are on an ongoing mission to make it easier and more intuitive to handle permissions in Webforum. Why? Because easier permissions means safer permissions by minimising the risk of doing things wrong. A while ago, we introduced project groups to facilitate setting up roles for permissions in the project. Last release, we made some simplifications for the permissions matrix for projects. Now, we take it a step further by automatically adding all project groups to the permissions matrix in the project. When a project group is removed its permissions also disappear automatically.
