bisonw: Make it easier to run app as a service.

[JoeGruffins]

Some users would like to run bisonw as a service. There are three things specifically that would help make this a better experience for them.

1. On shutdown we require a y/n input on shutdown if the user has active orders. If one is running as a service/daemon then they cannot send y and the process will be killed anyway, possibly resulting in data corruption. We should allow building with a flag that disables the last prompt.
2. Login requires navigating to an rpc or the web server after starting. We could allow passing the password by flag as well to log on after start up without another step.
3. mm cannot be started automatically. Again we could just start all bots with a flag.
