Splitted keepass2android project into

- keepass2android: UI stuff only
 - Kp2aBusinessLogic: Password-Database related algorithms (even though tied to android, no UI required here)

Removed dependencies of logic layer to static Application, Resource class or other UI stuff
Added MonoDroidUnitTesting (not yet used, will be used for testing logic layer)
