All emails sent from the chatter start with "Re:" followed
by the name of the record. The name of the record alone is sometimes not enough for
the followers to understand what the mail is about.
Additionally, "Re:" does not make sense when starting a conversation.
This commit gives better default subject
for event registrations and allows thread models
to override the default subject of messages.
This also removes "Re:" from default mail subjects.
