[Building Sakai] Announcement Entitybroker and ReferenceParseable

[Aaron Zeckoski]

The "/" is essentially a reserved word for all intents and purposes.

I have done something similar to "abuse" things by doing:
siteId::entityId for the memberships provider.

Not completely ideal and if I were doing it now I would do:
memberships/site/{siteId}/{membershipId}
