SQL: Added tags_vn.ignore column and updated queries to respect this

This is the first step in adding support for overruling tag votes by
moderators.

Also removed some unused options from dbTagStats(); the
tag-vote-stats-by-user pages have been removed in the previous VNDB
update, which was the only page using these additional options.
