Petabridge.Cmd.Common 1.1.4

Minor Version Release for Petabridge.Cmd** This is a pretty significant set of feature improvements for [Petabridge.Cmd](https://cmd.petabridge.com/). New Commands** In 1.1.4 we've added two new commands to the built-in pallettes contained inside Petabridge.Cmd.Host: `net clients` - gives a printout of all local and remote clients connected to the current host. `net drop-all-clients` - a somewhat dangerous command intended to be used by ops teams that rely on lots of `PbmClient` instances internally. This command will automatically terminate all clients connected to the current host. Clients will receive a notification that the host has disconnected from them. Other Changes and Improvements** `actor hierarchy` now prints out all `/system` actors by default - to turn this behavior off please pass in the new `-e` parameter to exclude `/system` actors from your query. Fixed stability issues with `IPbmRemoteClient` not always shutting itself off cleanly on both the server and the client.
