Moved javascript function for Cancel from new Feedback form to just
before the one for Save.
Can have a create and an update form open inline at the same time for
action items, so have changed the actionitem_save and actionitem_cancel
ids to be classes.
Fix bug in building the correct url for editing actionitem:
Was: replacing the first zero with the actionitem pk (no good if your
Decision pk contains zeros)
Now: replaces first ocurrence of '/0' with actionitem pk, which should
only match our placeholder zero.
Added trailing slash to actionitem url patterns so that requests to
those patterns with trailing slash will work (would return 404 before).
Requests to those urls without the trailing slash will still work (because
of global APPEND_SLASH setting).
