Have Vulcan show a logout page when a session times out

[wdower]

Right now, Vulcan will not kick you back to the login page until you actually try to do a CRUD operation. So we can be looking at the project view, try to create a component, and only be kicked back to the login stage when we actually try to submit the new component (thereby leaving the page and losing our work).

Vulcan needs to show a logout screen as soon as the session breaks.

This doesn't necessarily have to be a specific logout page and can just take you back to the login screen with maybe a message that the user has been logged out due to inactivity.
