[patch] bugs.php.net boolean search

Hello- Here's a patch to allow boolean search within the bugs database: http://www.boogle.com/tmp/bugs_boolean_patch1.txt Checkbox options are: Any: Current behavior. Results contain any of the terms All: All terms are required (uses + operator) Raw: Allows user to use own mysql fulltext boolean lingo, like +, -, *, ~, etc. It's a simple patch and tested locally. Look it over, anyone feel free to modify and/or apply it! ;) Regards, Philip Note: The patch is specific to this task, I tried not to alter anything else.
