Took care of a couple bugs and added a couple new features!

1) Fixed a bug with 1.14.3 VillagerTradeCheesingProtection that would prevent new villagers from ever being able to pick up a trade. Now a villager can change professions as many times as desired UNTIL a player opens a trade window, once that happens the villagers trades will become locked.
2) Fixed a bug that only affected minecraft 1.10 users that would prevent players from being able to pick up items off the ground.
3) Added a user requested feature to allow IllegalEnchantments for very specific items. To add a specific item to the whitelist do the following:
a) Turn off Fix Illegal Enchantment Levels (/istack toggle FixIllegalEnchantmentLevels)
b) get a copy of the item you want to whitelist hold it in your main hand.
c) use /istack enchantwhitelistmode (to enable/disable whitelist item copy mode)
d) left click with the desired item in hand, it will be copied to the whitelist including lores, name and enchantements
e) re enable FixIllegalEnchantmentLevels (/istack toggle FixIllegalEnchantmentLevels)
4) Added a user requested feature to toggle set up EndWhiteList and NetherWhiteList as either a WHITELIST or a BLACKLIST, whenever EndWhiteListMode is set to false, the whitelist will behave as a blacklist, meaning any entities added to the list will be BLOCKED rather than allowed to pass through the portal.
