Merge lp:~codeforger/bitcoin-app/wallet_migration into lp:~dreamsorcerer/bitcoin-app/python

[Michael Rochester]

Added support for importing all old bitcoinj bitcoin addresses into the new pycoin BIP32 format.

Added support and integrated loading the old address book format and all labelled addresses.

Added support to remove the old data files to save space on the device.

[Michael Rochester (codeforger)]

Reading the first commit message will let you know how to install the required extra dependencies this merge brings in.
