Title: Offers / Enable alternative ways of limiting an offer

At the moment, an offer is limited only by the date range. We should add alternative options including:

* A global limit on number of applications (eg offer can be used 100 times)
* A user limit on applications (eg each user can use this offer only once)
* A basket limit on applications (eg each basket can use this offer only once)
