Added preliminary support for meal-plan week calculation
Added a swipe-recording feature that can help the user keep track of how many swipes they have left (and then compare that with how many they should have left).

Fix issue #22 (ampersands being displayed incorrectly).
Moved the swipe calculations and recording to a separate class to help prepare for widget support.
Fixed text alignment issue #25.
Fixed debugging error when uploading to Google Play
