tag_slugin and some sanitization

Support AND operator

Needs a lot of testing, especially the intersections.

(In [17244]) categoryand, tagand, tag_slugin, tag_slugand support. fixes #16157

[ryan]

Looking good here. If a tag that doesn't exist is specified in an intersection, that tag is ignored. It won't be required in the AND. I think this is different than 3.0, but quite edge case.

'tag' is also missing.

[ryan]

(In [17272]) Resurrect 'tag' query processing. see #16157

This was broken in [15613].

I have an issue that arose since release of 3.1 whereby

$args = array(
     'category__and' => array($_GET['neighbourhood'],$_GET['venueType']),
     'posts_per_page' => -1
     );
query_posts($args);

used to work, but does not now. I am cross-posting here in case it is of relevance to the changes made in this ticket - ​Support Forum Post Thank you for any help.
