Changes to the config.yml to support permission based lasso.
Mobs can be leashed only if they are permitted under the lasso.mobs section in the config.yml. Additionally, if the lasso.perms option is set to true, then each mob will be disabled from lasso unless that permission is given to the player or group (i.e. lasso.chicken).
The permissions name names will be similar to the names in the mob list.
Enabled support for all mobs. config.yml will include them by default, so need to disable if you don't want Ghasts, Blazes, Withers, EnderDragons, fish and mites to be leashable.
The behavior for Right-Click and Shift-Right-Click have changed when holding multiple leads.
Right-Click on a fence post while holding one or more leads will place all leads on the post.
Shift-Right-Click on a fence post while holding one or more leads will transfer a single lead to the post. Additional leads can be transferred by Shift-Right-Click on the post (not the knot).
Right-Click on a knot with an empty hand will transfer all the leads to your hand.
Shift-Right-Click on a know with an empty hand will transfer a single lead to your hand. Additional leads can be transferred by Shift-Right-Click on the knot.
