YetAnotherConfigLib

End-user changes

• Smooth category scrolling
• Individual reset buttons for every option
• Fix bug where option lists that just went over into scrolling scrolled extremely slow.

Developer API changes

• Actual Config API to save and load fields in a class automatically (documentation)
• Separate Dimension into Dimension and MutableDimension
• Make dim private in AbstractWidget so mods can't change the dimension without setDimension
• New Option API method isPendingValueDefault to check if pending value is equal to default value of binding
• Fix Option#requestSetDefault and Option#forgetPendingValue implementations weren't notifying listeners
