KISS – Keep Inventories Sorted, Simple

• Special case sorting (shulker boxes, player heads, enchanted books, tools) is now applied regardless of sorting type (ID, name, category, mod) (#5)
  • I still consider dropping different sorting types altogether, as I personally see no benefit to anything other than ID sorting with special case handling for best results; please let me know if and why you depend on other sort types
• Defining your own ignore lists now actually overrides the default ignore lists
  • On the other hand, when not overriding them, the defaults are now properly respected; the crafting table is ignored by default, meaning you are no longer at risk of accidentally sorting your player inventory (despite having all player inventory sorting options disabled!) when having the crafting table open (#2)
  • While testing this I noticed that the "hide sort button" ignore list doesn't seem to work properly; I don't think this is due to my changes – I have the buttons always disabled, so not a high priority for me to fix; might still remove the buttons completely (and/or the ignore list feature)
• The default action for the middle mouse button in Creative Mode ("pick stack") is no longer blocked by the mod (#6)

There should be no other functional changes despite a fair bit of code refactoring. That refactoring should make it a bit easier to work on future improvements (special case sorting for sherds, trims, ominous potions and more; better handling/grouping of certain blocks in general – e.g. sorting all different colored concretes together instead of mixing them with wool/terracotta/glass of the same color).
