[TiddlyWeb] provide information about authenticated user

[FND]

While the current challengers (OpenID, cookie-based) supply a cookie containing the authenticated user, it is not guaranteed that all challengers create a cookie.

TiddlyWeb should thus provide a way for the client to retrieve the respective username.

This information could also be used by TiddlyWebConfig? to set config.options.txtUserName.

One option would be for tiddlyweb.web.sendtiddlers.send_tiddlers to set the txtUserName cookie to environtiddlyweb.user?usersign? when sending the wiki serialization.

Not entirely sure this is "best" but it is a solution.

Replying to cdent:

Agreed; this seems like a good solution for now.

Another option is a /status url that returns a json rep of various info about the server's current state, including current user, version

If done as a plugin we can play around with it for a while.

A status plugin has been created:  http://tiddlyweb.peermore.com/wiki/#%5B%5Bstatus%20plugin%5D%5D
