fix set_key wsapi on authority, now properly associates a NEW key with an EXISTING email address owned by the currently authenticated user

implement 'identity sync' which basically triggers client re-keying of identities that the server knows about but the client doesn't.  Also invalidates ids that the user has removed (probably on another device).  Also this is the proper place for revocation and key refresh to occur.  one transaction + one per key reset (though that could be consolidated)

refactor code a bit to move connect setup into run.js of the specific server.  this will make it easier to figure out how to run servers both standalone and in the test harness

add 'this is not me' link to clear localStorage/logout.  add 'addEmailAddress' client flow to associate a new email with your account.

implement kick over from create acct to signup for account if acct already exists.  also focus the users input properly when they land on the auth dialog

implement localstorage caching of ids and pubkeys, stub out assertion generation crypto and use it from client code

implement polling in dialog and related wsapi in server, this is when waiting for email verification, subsequent to sign up

migrate to the connect framework for node.js, specifically this provides session management middleware
