& ports()
Syntax: ports(<player name>)
This function returns the list of descriptors ("ports") that a
player, specified by full player name, or by dbref, is connected to.
Only Wizards may use this function; if a user lacks the privileges,
or the player is not connected, an empty list is returned.
Otherwise, a list of ports is returned in order of most recent
connection to least recent connection. These ports correspond to
those given by the session command.
