[feature/remove-db-styles] Remove style.php DB storage.

Browse source 
Removed all use of the DB for serving/caching the theme from style.php,
acp_style no longer stores the theme modified time either.

As a consequence currently all stylesheets will be served through style.php
(with no caching) until imagesets are removed [PHPBB3-10336], then
they can we served as static files by HTTPd.
