As an editor I want to know if I'm in danger of unintentionally editing under an IP in order to not leak my IP.
**Problem:**
We need to warn people if they are editing under an IP.
**Screenshots/mockups:**
TODO Charlie
**BDD**
GIVEN a user that is not logged in
WHEN opening the Bridge
THEN a warning screen is shown to inform them and give the option to log in
GIVEN an anonymous edit warning
WHEN clicking log-in
THEN the editor is redirected to the login page
AND redirected back to the article they were editing
**Acceptance criteria:**
[ ] Bridge detects if an editor opens it while not being logged in
[ ] Bridge shows warning to non-logged in editors
[ ] Editor is redirected back to the article they were working on after logging in
[ ] If editor decides they don't want to login, Bridge proceeds with a normal editing workflow
**Notes:**
logging in
* log in screen opens in the same tab
* after logging in, user is redirected to article
* they need to re-click the edit button
