Made the app controller include the action by default. Added virtual callouts for data order and limit. Changed fields to use formatting, including a custom format for currency and id. Added a function for auto conversion from PHP variables to javascript. Fixed some minor bugs in the controllers already converted to jqGrid. Moved leases onto jqGrid.
