"keywords" meta tag removed completely.
"description" meta tag now is not set in system, every particular module should handle it by itself, meta tag is rendered only if not empty.
"admin_phone" removed from settings because it is not used anywhere within system.
Removed update stuff for very old versions, which can't be updated directly to current version anyway.
