Give IMembers a unique member id. We have to do this in order to give them a

path at the root of the resource tree (i.e. /members/X) and because when
members can be subscribed by their IUser record (for preferred address), their
canonical location cannot contain the address they are subscribed with.  When
their preferred address changes (without otherwise touching their membership),
this address will change and that's not good for a canonical location.

Other changes:

* Added IMember.member_id attribute
* Added ISubscriptionService.get_member() so member records can be retrieve by
  member id.
* We can now get individual members by id via the REST API.
* Extend the UniqueIDFactory so that it can take a 'context' (defaulting to
  None).  The context is only used in the testing infrastructure so that
  separate files can be used for user ids and member ids.  Otherwise, we'd
  have gaps in those sequences.
* When *not* in testing mode, ensure that UIDs cannot be reused by keeping a
  table of all UIDs ever handed out.  We *should* never get collisions, but
  this ensures it.
* Clean up mailman.sql
