Right now making it its own dialog, not sure if this is correct or not yet.

Only showing the button if the user is actually authenticated.

Conflicts:
	browserid/static/dialog/controllers/setpassword_controller.js
	browserid/static/dialog/resources/browserid-network.js

Conflicts:

In dialog_controller, using this call instead of the manual calls to BrowserIDNetwork.logout and BrowserIDStorage.clearEmails

Adding cancelUser to browserid-identities and removing the work to sync emails from BrowserIDNetwork.

Also updated the globals declarations at the top of all the files to only declare the ones actually used for that file.

Since the relay is only two files, right now in compress.sh concatinating just those two files.

issue #265

some updates to the dialog from a couple of days ago

Conflicts:
	browserid/static/include.js

Fixes a problem when selecting an email, an email was not passed.
