Functional on 1.16.5

Requires plotsquared... as always.

Just a quick update for the most recent PlotSquared API version- nothing else though.

• There is now a reload command! /plotguardreload
  
• You can now add certain entities to block player interactions with! For example, if you add IRON_GOLEM to the list, players can then NOT interact with that entity.
• I added the spigot API links into the configuration so you can choose from any of the materials and entities.

YOU MUST DELETE YOUR CONFIG.YML AND LET IT REGENERATE! I'm very sorry, but it has to be done for the new fields.

Thank you to TheGrayGorilla for bringing this addition to my attention!
