Addition of swipe action on med-reconciliation, pop-up navigation, and additional functionality

The main changes in here are to enable a two-page medicine reconciliation process. I've reused elements of the UI interface from the previous version.

In addition, I've added a pop-up navigation menu, which allows the user to quickly move between stages in the medicine verification and reconciliation pathway, although some functionality here hasn't been fully implemented yet.

This version now also includes jquery-mobile, to enable the swipe procedure.
