[ticket/13808] search_body_form_before
Extensions may be designed to add secondary search options,
such as Google search in the search_body.html.
There are no events in the searchbody, so this should be merged.
[ticket/13787] Remove duplicate entry of poll_delete in prosilver template
When options are shown and poll delete is allowed, the option to
delete
polls is shown twice. This is fixed here by moving the if poll
delete
check out of the outer if, wich makes it also more consistent
with the
new event.
