added a preference to display the workflow form on either the node editing form
  (which we've always had) or when adding a comment to a node
refactored nodeapi implementation into workflow_transition() so we can reuse
  code from either the nodeapi or comment hook
uninstall now deletes the two actions provided by workflow.module
  (workflow_select_given_state_action and workflow_select_next_state_action)
  from actions table if actions is enabled
only show node type/workflow assignment if a workflow has been defined
