Hiding the button to 'add new list category' so lists are controlled through the list cpt rather than the lead cpy category. I don't think we have reverse synchronization setup for adding lists via lead category taxonomy. That's why the taxonomy category is hidden in the leads cpt.

Also comming out the wp_list_table metabox include for showing a list table of what lists the user belongs to. This looks like a feature that is dependant on the rules plugin and if it harms flow we can come back and address it later.
