Tag templates no longer work with tag-{$tag_name}

[cogmios]

Tag template pages e.g. "tag-wordpress.php" to not be called or found. See ​http://edward.de.leau.net/tag-pages-and-wordpress-27-20081011.html.

I dont know the status of the function so I consider this a unit test report, but a pretty large bug.

Nothing is wrong with locate_template.

The fact is that the code in 2.6.x allows for textual tag templates 2.7 for some reason expects them to be numeric tag ids.

The change is in get_tag_template() which now wraps an absint around the result of get_query_var

Looks like that absint was an accidental copy and paste error when I did [8624]

(In [9125]) Fix regression in get_tag_template(). Tag templates are referenced by tag name not id. Fixes #7865.
