[wp-hackers] preventing new tags from being entered.

[Helen Hou-Sandi]

Remove the metabox, make your own replacement that only allows selection,
and hide the admin screen (/wp-admin/edit-tags.php?taxonomy=post_tag) from
non-editors/admins. Can also only do the metabox switching for
non-editors/admins.
