QuickShop-Hikari

This is a small optional bug fix for Hikari.

Bug Fixes

1. If user upgrading from Reremake legacy version (which released before Minecraft 1.16 updates), the shop sign won't be correctly upgraded or recognized. (It fixed in 3.6.1.5 and all exists signs should be recongnized and upgraded after user click it.) Thanks for @Magma from server ria.red for reporting it (Well, that's probably what happens when production environment servers are upgraded only once in many years XD, I recommend that all server administrators for set up a upgrade schedule for updating plugins).

Other Stuff

We're working on Hikari-v4.0.0.0 and focus on performance optimize (multi-threaded, async, caching etc.), improve loading logic, boost startup speed and improve user experience so it will ready for large network.

Also, this is a great opportunity to make feature requests to us (because this change to the API will create changes, and once the API is fixed, it will be difficult for us to make major feature changes)
