Release of v5.0.0-rc3

Improved the Schema Table update engine (more). Fix autoloader timing, and loading. Implement the Joomla Powers in JCB code, to move away from JClasses. Remove the SQL update, to only use the Schema updates of table columns to avoid collusion. Fix the admin.css file loading on dashboard. #1112. Fix dynamic get data-type default to 0. #1110.
