AppCache + Quota integration

* Notify the QuotaManager of accesses and modifications to the amount of storage utlized.
* Implement the QuotaClient interface so the manager can query the appcache for usage and delete data.
* When storing appcaches, use QuotaManager GetUsageAndQuota and respect the limit.
* Remove the old and unsed support for storing per-origin quota values in the appcache DB.
