List existing resellers

When run with no parameters, this program simply displays a reader-friendly table of existing Virtualmin resellers. The only supported options are --multiline, which causes it to show more details about each reseller in a format suitable for reading by other programs, --name-only to dump just a list of reseller usernames, and --simple-multiline to display details that can be computed quickly.
