Views integration

Hi, I added a new views_data Handler to the Access Token Entity and it works with any entity type configured in the Access Unpublished settings form.

renew and delete operations updates to work with views.

the js library is not added for default for the view operations field, this patch attaches the library in a new access token operation view handler.

access_unpublished_copy_raw_url view field added and url query parameter removed from view operations field

Clean up patch

user_id filter id updated from numeric to username. This is necessary to have the token access author as autocomplete field.

This patch is working great and is essential on a site with lots of tokens. It allows you to make a better admin page so that admins can search by node title, filter by content type, sort, and anything else views can do.

Marking as needs review.
