#58 Error when searching in multiple fields

[Tony]

Search in phpwslistings is possible with the built-in
search option of the module.
But there is also the option to serach with an url,
e.g. /index.php?
module=phpwslistings&LISTINGS_user_op=Search
Listings&LISTING_<field>=<criterium>.
This works great for text and select fields but not for
multiple select, radio buttons and check boxes.
Then the url returns an empty string.
The cause of this was an unserialize statement on line
696 of ListingManager.php and a corresponding bug in
the match function in Listing.php
I fixed them (and added 1. the possiblity for assigning
categories to Listings and 2. a summary field).
