This is an attempt to commit the changes made to Electrum-BTC to morph it into FLO, on top of the latest Electrum-BTC codebase at the time of writing. The code has become messy pulling upstream changes and its become difficult to debug issues
if NaN coin price is cached, historial acquisition prices are not shown
correctly since the historial prices are requested after the full

The changes made in this commit make sure the transaction comments or floData are being sent out of the wallet.
It still has some errors left though, related to verifying SegWit address.
is_mine: wallet expects get_address_index to work
imported wallets: history did not include addr keys after creation
deterministic wallets: get_addresses() should be sorted in derivation order
