Title: Declaring roles association callbacks from the rolify method

1. Allows passing options without requiring declaration of `:role_cname` (setup for declaring callbacks with ease)
2. Accept association callbacks `:before_add`, `:after_add`, `:before_remove`, and `:after_remove` into the `rolify_options` via the `options` argument.

Specs are included for the callbacks.
