Prevent spamming emails for daily reservations

We mark all occurrences of a daily reservation as notified after the
first email is sent.
Clean jStorage when booking is done
Use the new way to pass vars to a tpl
Fix exception classes
Improve reservation history display
Add reservation modification
Use an ARRAY for edit log entries

Using a ```-separated string is *very* strange and would break when some

without recreating it, use this query:

ALTER TABLE reservation_edit_logs
  ALTER COLUMN info TYPE varchar[] USING string_to_array(info, '```');
Fix typo
Reservation cloning
Use i-buttons on room details page
