Long term there will be a proper fix for the problem of the same Python file being able to be both a library and an executable program: On core-updates, there's a wrap-script function which will do the right thing in both cases. After master is merged to core-updates, we should use it for trezor-agent. For now, the workaround is fine. Applied to master. Thanks!
