Noteworthy:

• Transactions are native P2WPKH transactions (as can be seen by the bech32 address in listtransactions output above)
• confirmations: 101 is because of our hack to consider the first 100 blocks to have a mature coinstake... there are not actually a 100 blocks confirming the genesis block's transaction :-X
• importmasterkey backs up the current wallet, even if that was just created and is empty (you'll end up with wallet.dat~something in your working directory), there is a ticket for that: detect empty wallet or create new wallet #40

This is not to be merged, it duplicates #212 (on purpose)
