Custom enchantments

[+] Added custom enchantments. Basically, you can create your own enchantments and use on enchantment tables and anvils. The tutorial on how to create one is at top of the topic.

#Expressions:
level of custom enchantment %custom enchantment% of %itemstack%
[all] custom enchantments of %itemstack% #You can add, remove, whatever, as your wish
%itemstack% with custom enchantment[s] %custom enchantments% #Returns a itemstack

#Condition:
%itemstack% has custom enchantment %custom enchantment%
#You can check if a item has a specific custom enchantment or
#custom enchantment and level

[+] Added chat tag for Legendchat.
Now you can have personalized tags to your chat. It's a feature of the plugin to set custom tags for a player. If you don't know about it, wait until I put these expressions at documentation with usage and examples.

#Expressions:
chat tag %string% of %player% #Return the value of some chat tag
chat tags of %player% #Returns all customized tags that used with expression above

[#] Temporary fix for Landlord. If you have issues after this update, please wait just a little. Else if you don't have it, just ignore it. ;)

[#] I'm quite sure that I fixed something that I don't remember now.
