Reduce terminal spam

[AdamISZ]

Two main sources of terminal spam spring to mind: every 3 second gettxout output during waiting for confirmation, and low level twisted log output for the http requests. This is partially addressed with log levels, but should still be investigated. Logs are in /logs directory which helps. May want to prettify also. No urgency with this.

Todo: remove twisted logging in non-test runs. And add back some simple logging to show state in the wait between phase 1 and phase 2, the above commit removes all indications of what's happening with default INFO level.
