New CCODE function to query a users ip address from kod.

New CCODE function to query a users ip address from kod.  This function
returns the integer representation of the ip address (16777343) and not dotted
decimal form (127.0.0.1).  The integer form would be preferred for fast
calculations where a string compare would waste processing power.  Can add
either a ccode function that returns a string for dotted decimal form
later, or process the integer in kod.
