Adjustable Margins

Hot on the heels of the previous release, this one allows you to customize how close to the left or right edge of the screen you want the clock to show.

A new setting hor_margin has been added. The value can be auto (default) or a whole number of pixels.

This release also removes the .txt extension from the uninstall file, so it will not be imported by the Kobo software. It is safe to delete the old uninstall.txt file.
