to using the Google Calculator.

Added ability for jenni to recognize changes by other people for s///
without a colon being used as a deliminator.
Improved ip/host lookup module

This change significantly fixes and changes the output and handling of
the .ip and .host. It currently does not account for IPv6 geolocation
lookup. This will be added in the future.

actually equaling each other.
