A big change that doesn't affect functionality is that the prime number data now resides in a separate package called rpnChiladaData. This data rarely changes so there's no reason to download it.

A major bug was uncovered after almost a year. rpnChilada thought there were 51920.97 seconds in a day because of a typo. This has been fixed, and I figured out how to detect other similar problems if they exist. This change will be implemented in the next few days.
