Add some javadoc comments

Several packages were moved from BJC-Utils to esodata. This makes the
necessary adjustments

Cleanup some warnings

Issue popped up in DieMods where the compiler was failing to allow what
looked like a correct cast. Solution was to switch to using a lambda,
instead of Comparator.naturalOrder()

This adds all of the remaining missing die modifiers, as well as a few
base die types that were missing.

This starts work on a rewrite of the dice rolling system to better adapt
it for more features
