Add --hostnameonly option to floaty list --active

Browse source 
Adds an option to the `floaty list` subcommand so that, when listing
active hosts, floaty will output just the hostnames, without any
additional information or formatting. Hostnames will be separated by a
newline.

This functionality is primarily intended for consuming by tooling (such
as the tab completion scripts).
