PROV-845 Fixed handling of List attribute lookup fields in advanced search forms

For more info see pr/88
PROV-845 Hopefully fix the advanced search list attribute lookup issue for good

We never actually need the "{".$pa_options['element_id']."}" kind of
placeholders in the form elements when dealing with a search, so we
don’t bother inserting them.

Add mtime= URL parameter to local JS and CSS.

For local files, use filemtime() to grab the modification time
of the file and append it as a URL parameter.  This causes browsers
to cache the file until it is modified.  These files can therefore
be configured to be cached forever by the browser, as any modifications
will be automatically retrieved as there will be a new URL whenever the
file is modified.
