Add limits to license and enforce Project limit

[knolleary]

Closes #776 #780

This PR builds on #946 - that should get merged first.

This adds claims to the license to cover projects, users, teams and devices.

If no license is applied (CE edition), they default to the values described in #780

If a license is applied, it uses the values from the license, defaulting to 0 if not present.

When the platform starts up, it reports on the counts:

In the second commit, changes are added to enforce the Project limit. This is done as a hook on the model itself - so any code path that tries to create a project in the database will be handled.

The UI side does a fairly default Alert notification that the license limit has been reached. That can be refined as I work through policing the other limits.

NOTE TO DEVELOPERS

Once this PR is merged, you will need to update the development license you are running with locally otherwise you will no longer be able to create projects (unless you run with no license at all). As before, this is provided in forge/licensing/index.js.

Just noticed the UI tests are failing - am investigating

[knolleary]

Ah - the test attempts to invite a 4th user to a team. Which is not possible anymore due to the new limits.

Kinda proves it works. :)

Reordered the test a bit so that it never tries to exceed the team membership limit.
