Revert to using dynamic canonical url

Fixed the issue from 3684d931b336fc16810bc81f3888eac23813a447 via a
301 redirect in Apache configuration instead.
Use combined CSS and JS when !localhost()

combined.css and combined.js use mod_includes to combined resources.
For development (when viewing a local copy via 127.0.0.1 or localhost), use
un-combined sources. Otherwise, use combined.
