NFC beam the repo in RepoDetailsActivity

Browse Source 
This is the framework for easily swapping repos.  The idea is that a user
can send the URL with the fingerprint for trusted bootstrapping of the repo
on a new user's device.  This will be essential for p2p repos provided
by Bazaar/Kerplapp.

The required NFC APIs were introduced in android-14. So android-14 and below
skip the NFC stuff.
