edit-tags.php add_tag_form_fields hook

[jfarthing84]

There is a hook for add_tag_form_pre and add_tag_form (which is fired after the the form). I believe a 'add_tag_form_fields' hook should be added as well, just like in the edit-tag-form.php file. This is so plugins can add custom fields for custom taxonomies. While on the subject, it would be nice for all the fields and buttons on the custom taxonomy page to display the taxonomy name instead of "Tag" (ie. "Add A New Tag" or "Tag Name".

See #11838 - I've merged categories into the edit-tags form, so that'll get fixed shortly in trunk.

I'll also need to fix up and standardise the hooks provided, so will address this in that.
