This release addresses various reported issues:

• Fix IllegalArgumentException when feeding an entity a single food item (#13)
• Fix IIlegalArguementException when the MergeTask is ran.
• Fix NullPointerException when the drop blacklists are used (#11)
• Change stacking tool material to a bone to avoid interference with other plugins (#9)
• Fix NullPointerException when right clicking entities with no item in hand, caused by stacking tool metadata checks (#10)

I am aware that some people are facing issues with stacking of spawned entities - this is under investigation at the moment so hopefully an update will be released soon.
