Given `proxy` & `router` processes have been merged, `launch-proxy`,
`launch-router`, `stop-proxy`, `stop-router` do not make sense any more, and
should just be `launch` and `stop` with the appropriate flags.
Caveats:
* TLS files must be present on the target server (and readable)
* TLS file paths cannot contain spaces
* TLS file paths must be absolute (i.e. cannot be relative)
* Bash argument parsing is terrible
The code is quite messy, but particularly the argument parsing and
volume-mounting. Also, it doesn't support args with spaces, or
non-absolute file-paths.
