Subject: [PATCH] Make Events create Dates on demand

My test account had 37MB (shallow) of Date objects knocking around
in memory. This gets rid of them. I can't see any appreciable
difference in the time taken to switch rooms (where now we recreate
a bunch of Dates that previously would have been cached).
