Change PeerGroup.broadcastTransaction() to wait for propagation.

Browse Source 
It means a send won't be considered completed until it's accepted by the net.
Also is for the case where you receive a transaction (eg, via Bluetooth) and
you want to broadcast it such that you can know it's valid.

Make WalletTool use --peers instead of --peer, a comma separated list of
addresses to use. Remove the crappy sleep after send now we can wait.

Resolves issue 167.
