ENHANCEMENT: Remove "Create Workflow Item" option when user is not logged in/not workflow authorized/has no workflows
DESCRIPTION: Currently, if a user is not logged in but the WORKFLOW addon is enabled on a channel, the option to create a workflow item from a post/comment is available. This should only be available if (1) The user is logged in. PERHAPS also adding a JAVASCRIPT fetch the logged in user's home "hub" to determine whether the logged in user has any workflows would be good as well.
DISCUSSION: The WORKFLOW addon is a bit complicated due to the distributed/decentralized environment in which it operates. It uses JS to communicate both with the site being viewed along with the user's home site and/or the site that hosts the workflow that "contains" the item being referenced. Thus, there are up to three different hosts/hubs involved in the communications stream of interacting with a workflow item.
