ac-html-enable and ac-haml-enable for enabling ac sources

Why need ac-XXX-enable? Because
1. ac-source-XXX-attribute-value require 'font-lock-string-face removed from ac-disable-faces list
2. right ac-source order ac-source-html-attribute-value must be first, user might wrong setup
3. In future other minor ac setup might be done wothout need to disturb user for configuring.
