Subject: [PATCH] setup main FDroid screen to NFC Beam the FDroid.apk

This pre-configures a file:// URI that points to the installed location of
the FDroid.apk.  When users put two devices together, and touch the screen
on the device with FDroid on it, it will "beam" over the APK, and prompt
the user to install it.
