Confers or removes the ``player object'' status of the given <object>, depending upon the truth value of <value>. If <object> is not valid, E_INVARG is raised. If the programmer is not a wizard, then E_PERM is raised.
If <value> is true, then <object> gains (or keeps) "player object" status: it will be an element of the list returned by `players()', the expression `is_player(<object>)' will return true, and users can connect to <object> by name when they log into the server.
If <value> is false, the <object> loses (or continues to lack) "player object" status: it will not be an element of the list returned by `players()', the expression `is_player(<object>)' will return false, and users cannot connect to <object> by name when they log into the server. In addition, if a user is connected to <object> at the time that it loses ``player object'' status, then that connection is immediately broken, just as if `boot_player(<object>)' had been called (see the description of `boot_player()' below).
