======Synopsis:======
$iptolong(<dotted-quad>)

======Technical:======
   * If the <dotted-quad> value is omitted the empty string is returned.
   * The <dotted-quad> value is taken to be a dotted-quad ipv4 internet address of the form "A.B.C.D" where A,B,C,D are integers less than 256.
   * The return value is the NETWORK ORDER integer equivalent of <dotted-quad>.

======Practical:======
This function does the reverse of $[[longtoip]]().  The DCC handshake uses
'long's to swap ip addresses.  You could use $[[convert]]() to convert your
hostname to a dotted-quad and then use this function to convert it to 
a "long" value which would be suitable for use in a DCC handshake.  Why
you would do such a thing is not certain but this function is included
for completeness sake.

======Returns:======
The "long" integer IPv4 address equivalent of <dotted-quad>

======Examples:======
$iptolong(127.8.4.3)			returns "2131231747"
