Title: Quotas for channel options - Closes #216

* The channel quotas are only configurable by the administrator so the
function is accessed via the "Site Settings" menu item.

* This feature tracks how many channel options each user has used up.
We therefore keep track of each user's usage each time a channel option
is added/removed. When a user maxes out the limit, the API returns a
status 400

* The quotas are only for channel options that are specified via a
textbox and the premise is that users specify one option per textfield.

* On the UI, each quota item is saved individually:
