Calculate bills and hits needed to add 1 to the George Score

The George Score at Where's George is based on the following formula:

GS = 100 * 
     (sqrt(log(BillsEntered)) + log(TotalHits + 1)) * 
     (1 - DaysInactive / 90)

This Perl script calculates how many bills you need to enter or how many hits you need to get to increase the George Score by 1. It does that two ways: by using derivatives and by solving the George Score equation.
