Renames the app (label, texts, User-Agent, PRODID, APK) and uses the new launcher icon pack
(ldpi to xhdpi, master in art/) instead of drawing one at build time. Reminders show a white
calendar glyph in the status bar (stat_notify, 18-48 px) instead of the system's colour
alarm clock, which didn't fit the Gingerbread bar. The package name, database and signing key
stay, so it installs over GingerCal and keeps its data.
