Fix taxonomy term ID field, filter and argument for term views, which were incorrectly keying off of term_node.

#311745 by mooffie: Incorrect use of replaceWith caused invalid data sent through attachBehaviors().

#308137: Filters were incorrectly checking for current user permissions on header/footer/empty text.

query::add_field() called ensure_table too aggressively and could cause aliases to improperly overwrite already existing tables.
