added android project
removed unused files
added gson and yodatime dependencies

- gson is used to serialize objects easily
- datetime is used becuase java's built in date is severly broken
configurated the manifest file
created abstract base classes for activity and fragment.

The main reason for this is to supply helper methods common to all
fragments and activities in the app. It also makes it easy to change the
fragment implementation to one from the support library or similar, at a
later stage.
Created a custom application; can be used to initialize code before app is started
Created a coupon model class + xml to fit with it

The model only have a few potential fields atm. It should be used as a
basis for the actual coupon model.
added color and dmins value files
created a basic coupon fragment to show info about a specific coupon
created a basic coupon list fragment, to show a list of coupons
basic main activity implementation

The main activity acts as an entry point for the application, and holds
the fragments. It should handle all communication between the fragments
relevant to this activity. For the time being this is limited to the
coupon fragment and the list of coupons.
Created a list adapter (data structure for coupons)

The coupon list adapter holds the actual coupons. The coupon list
fragment uses this adapter as a model, and whenever the adapter is
updated, the list should also automatically update the view in the app.
