Update 1.8.3.9 - All Shops GUI window with filtering and sorting

This is a fairly small update with some bug fixes, and a whole new system for filtering and sorting all shops. Now you can quickly sort by item name and price. You can also filter what shops are being shown by their stock and the type of shop! (Also can use the search mechanism like before to find a specific item being sold)



Bugs have been fixed and features have been added!
These all come from the bugs and features you all have requested on the shopbugs page so keep the bug reports and feature requests coming! Here are the specific ones that this update covered:
