be able to move a session from one browser to another

A user should be able to move his Sūsen session from one browser to another, so that he can change machines and pick up where he left off.

There is no requirement to be able to work on the session from two browsers at once! So really what gets moved should probably be a copy of the session, rather than the session itself, to prevent conflicts.
