Checking for Bad Logins: Bad Login MM Query

Sometimes, the primer URL login may fail, eg. bad login. However, since the only error indication may be a ``Login failure''-type message and not a true HTTP error code, Webinator may not be able to detect this and might continue walking useless (permission-denied or ``Please log in first'') pages.

To help detect such a primer URL failure, a Bad Login MM Query may be entered. If non-empty, this is a Metamorph query to run against the HTML returned from the associated primer URL. If it matches, the primer URL is considered a failure, and the crawl is stopped for that particular site (other Base URLs will continue).
