Support retrieving project access rights via REST

By GET on /access/?project=<project-name> it is now possible to
retrieve the access rights of a project via REST.

Having /access/ instead of /projects/<project-name>/access allows to
retrieve the access rights for multiple projects at once by specifying
the 'project' option multiple times.

In future this REST endpoint may be extended to only return the access
rights for a certain user or group by supporting a 'user' and 'group'
option.
