FeatureBlock
Allows administrators to disable certain features of Minecraft.
What does it do?
FeatureBlock allows server administrators to disable features of the Minecraft server all through a simple configuration file. Examples of what is able to be blocked include wither boss creation, boat/cart placement, blaze spawning, weather changes and more.
Configuration
On the first run, a configuration file will be generated. Please edit this file, save it and relaunch your Minecraft server for the effects to take place. Throughout the configuration, nodes are logical. mob.* blocks the spawning of the specified mob if set to false, otherwise allows spawning when set to true. Likewise, mob.create.* blocks or allows creation of specified mobs. Nodes basically mean "can x happen?" true for yes, false for no.
When a new node is created, it will default to being allowed and will notify the console that it has been added upon plugin enabling.
