action_form.php: Pull out DB code

* Create new functions in pkgfuncs.inc.php with SQL queries from
action_form.php
* Centralization of DB code important in a future transition to PDO interface
* Flip logic of vote and notify XHTML button to use function return rather
than a more confusing NOT (!) logical operator statement
