Add autopilot history/settings page

[bryanvu]

Currently, autopilot runs in the background without exposing any details of its operation. While this is helpful and intuitive to beginners, it may be confusing to more advanced users who are unsure why channels and transactions are being created. An autopilot history page could be helpful in explaining what actions have been taken by autopilot.

Eventually, a settings page could be added that would enable users to tune the behavior of autopilot for their particular use cases.
