[option] Reorder tabs according to stack

For people who prefer to use the stack switching, would be nice to have tab order reflect the stack order instead.
The same goes to open files in the sidebar.

just like the application switcher in Mac Os x works
Maybe using tabs to represent the stack is not such a good idea since it would break the expected behavior.

This might be a more interesting solution: http://sublimetext.userecho.com/topic/106652-/
