Fixed filter setup when a module has more than one filter.
Fixed filter setup for site,admin and webapi modes.
Added CMS_AUTH_FILTER, and check if user is already authenticated, then skip following auth filters.
Added specific webapi handler classes for root, user, access token, ...
Added user profile system to the core module.
