Support for capabilities

Hi,
can you please support capabilities for pwb-brand taxonomy to allow proper user rights management?

I have modified plugin to follow WooCommerce capabilities by adding following key to register_taxonomy args:

'capabilities' => array(
    'manage_terms' => 'manage_product_terms',
    'edit_terms' => 'edit_product_terms',
    'delete_terms' => 'delete_product_terms',
    'assign_terms' => 'assign_product_terms',
),

Another possibility is to create own set of capabilities.

Thank you.
