Implement a command to travel the focusstack. This can be used like a jumpback.

However, it is a bit more flexible obviously. You can specify the
offset of the window you want to go to, to implement workflows like
the following:
 * Jump to mutt
 * Jump to irssi
 * Jump back ("focus 2" would be the command)
