Some Wysiwyg Forms have JS err / Not functional insert button

Wysiwyg applies itself to all filtered textfields, including those outside of a comment or node context such as you'd find in settings pages. In those situations the token insert button will still be there, but there will be a JS error re: missing token_insert_wysiwyg.

Looking at the code, this is because token_insert_wysiwyg_form_alter limits itself to node types of node_form or comment, where Wysiwyg doesn't. Suggested solution: Use the same approach Wysiwyg does for inserting itself.

Are you open to patches? I've got a project that looks to be adding a number of features that I'd love to kick back into contrib (UI improvements, Webform token support, etc)
