Lightweight Inventory Sorting

- Rewrote sorting logic to be able to sort bundles in
- Changed button textures to better fit the mod
- Added new sort type which will sort like the creative inventory is organized

**NOTE: IF YOU EXPERIENCE A BUG, LOOK IN THE LOGS FOR SOMETHING LIKE "Encoded Snapshot: <some code>".** 

If you send that code to us as an issue on github, we can help fix the bug! All it does it encode the information in the inventory at the time of the sort so we can later replicate the issue!
