Update 1.8.3 - Better displays, bug fixes, and release changes

New proximity based displays!
I have rewritten the display system to be per player rather than per world. Shop displays will now only show to players that are near them in the world and should be much less intensive on the client. I have done some testing on this but am very curious to get your feedback on if this is better than the old system. All of the calculation is done async so there shouldn't be too much extra server load but I am always looking for more feedback!

New build release idea!
In the past, I had declared that shop would only support Minecraft 1.13+ going forward. However, a member of the community reached out to me to commission a port for version 1.12.2. This was Shop version 1.8.2.10 and the individual was kind enough to allow it be posted to the main page. Because this port required extensive library changes, it actually opened up the possibility to maintain two different builds going forward. This is not necessarily a promised feature going forward as I still plan to focus primary features and testing on 1.13+ but since I have a full port for old libraries, I am exploring the idea of maintaining two branches of the project.

With this release, (and potentially releases going forward), Shop version 0.8.3 is a full port of Shop 1.8.3, but is meant for Spigot 1.8-1.12.2. This legacy support is not going to be tested before release in the same way, but you are still more than welcome to submit any bug reports on it here. This "legacy build" (0.8.3) will support Spigot 1.8-1.12.2 and the "primary build" (1.8.3) will support Spigot 1.13+. If there is enough interest I may continue to do this but I make no promises going forward.
