Polishing up the GUI

It takes me a couple more days to get Songbook Manager into a presentable form. Scouring the web to study the Android UI standards, UI tutorials from many websites, and downloading the free icons, I was able to get the app into a pretty nice presentation. By then the software has a main songbook screen, a favorite songbook screen, a utility screen where songbook can be imported, email,  back up, and restore.
