New Gestures and Category Creation

I added a few new touch gestures today. Each of works on the entire page rather than an individual item like swiping left and right. The goal with these changes is to allow users to take the actions at any point on the page instead of having to scroll to the bottom first.

- swipe diagonally from top left to bottom right: Mark Page Unread
- swipe diagonally from top right to bottom left: Mark Page Read
- swipe diagonally from bottom left to top right: Go to Previous Page
- swipe diagonally from bottom right to top left: Go to Next Page

In addition to those adds a bug that prevented creating new categories has been fixed.
