Fix the $servernum() function - no matter what string

you gave it, it would return the first server in the list
where server.itsname == server.name, due to a misplaced
variable.  It also returned an empty string for
$servernum(  ) when it should return the current server.

Also removed the useless function_serverport() function -
it was a character-for-character duplicate of
function_servports().
