Can delete much of workbench_events_ui.class.php and workbench_workflows_ui.class.php because of workbench_base_ui.class.php

Copying workbench_states_ui.class.php to workbench_base_ui.class.php because there is a lot of commonality currently in states, events, workflows.

Workbench moderation events are starting to work. Next I need to get rid of workbench_events as a separate module.

Adding an experimental workbench_events which is basically find-and-replace port of ctools_access_ruleset
