[feature/remove-db-styles] Removed database storage of style components.
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.
PHPBB3-9741
The bulk of database storage of templates is removed, rendering template
stored in the database as useless.
Theme database storage is reduced to a skeleton for full removal soon.
