Administering invitations permission is way too permissive.

Issue Summary

I need some of my admins to access admin/user/invite*, without letting them access 40+ other admin paths from core modules, as is the case now. I'm inclined to consider this a bug, although this is debatable of course.

Invite 6.x-2.0-alpha1 (recommendend for 6.x) and 2.x-dev use “administer site configuration” a couple of times. People who read a bit of code might be tempted to simply grant this permission to a certain role, not realizing the global impact.

Even “administer users” would be a better idea, but still too much to my taste…
