New command line interface

A new bitcoin command line tool has been added to make features more discoverable and convenient to use. The bitcoin tool just calls other executables and does not implement any functionality on its own. Specifically bitcoin node is a synonym for bitcoind, bitcoin gui is a synonym for bitcoin-qt, and bitcoin rpc is a synonym for bitcoin-cli -named. Other commands and options can be listed with bitcoin help. The new tool does not replace other tools, so all existing commands should continue working and there are no plans to deprecate them.
