Issue #2694339 by sanja_m, Berdir, CTaPByK: Handle hook_crm_core_activity_type_add_fields_alter() and hook_crm_core_activity_type_add_field_instances_alter()

Made the contact entity a d8 content entity
Added forms for edit and delete
Moved access checks to a access controller
Added a simple list builder

The list builder does not scale. Views integration is needed. This
was posponed until https://drupal.org/node/1740492 got done.
