(#280) Strip whitespace from venue fields

Prior to this commit, Calagator would allow venues to have leading or
trailing spaces persisted in the database, which would lead to venues
having postal codes such as `97209 `, thereby reducing the likelihood of
finding duplicates. This commit forcibly strips whitespace from venue
fields during validation by adding `strip_whitespace!` to the
ActiveRecord DSL, technically in the `before_validation` stage.

Fix too_many_links checking when updating events

The spec wasn't actually testing the update action, and the update
action hadn't updated @event at the time of the check, leading to
some confusion.
Fix events/_item for events with no end time

We don't actually require end times on events, though our form strongly
encourages it. The recent update to add schema.org markup assumed that
end_time would always be present. This was a fairly safe assumption, 
given that we haven't noticed it in production until now. :)
