it appears that -v verbose mode was unreachable via fl-monitor-ctl

Not sure if I've misunderstood, but it appears to me that it has been impossible to turn on the `-v` verbose flag for XML-RPC server when running them via a controller such as `fl-monitor-ctl` (unless you use foreground debug mode)

This patch allows you to pass `-v` to the controller and trigger just verbose logging, separately from foreground debug mode

Verbose logging logs messages of log-level 'debug'
