- Implemented e-mail subscription (new item notification).

- Updated DB schema:
  * New "subscription" table
  * EPerson: renamed "active" to "can_log_in", and added "last_active",
    "self_registered" and "sub_frequency" columns (unused right now, but
    easier to make the changes at once)
- Updated EPerson object to reflect table changes, and callers of EPerson
  object
- Removed MIT-only filters from web.xml
