You can now create menu items. You can now delete menu items. Renamed ID to MenuID on PanelMenuPage struct. Bumped the copyright year in a place in advance. The footer is no longer hidden in the Control Panel in Tempra Simple. Fixed the notifications URL, although that page still isn't implemented yet. Fixed config_default.noparse so that Travis won't error over that. Refactored some user queries.
