Support Gradual Ability Boosts Variant

It would be helpful if the module supported the gradual ability boost variant. Currently, you must be level 5 before the next column for boosts unlock, but it would be very useful if there could be a toggle for the gradual ability boost variant to allow you to start tracking boosts at level 2. There is currently no way to track boosts with the gradual boost variant in the character sheet and this would add a sorely missed functionality for those that use the variant.
