tmux window pane navigation no longer directional

[David Britton]

Issue is described in http://sourceforge.net/p/tmux/tickets/122/

When you switch panes in an even "tiled" split (say, 2x2, 2x3 or 3x3) a MRU type algorithm is used to determine where your movement goes across a split boundary.

This algorithm works fine if your splits are uneven, but with even/aligned splits, it's a pain and unexpected. This issues has been fixed in upstream, and would be nice to include in vivid so this behavior doesn't go out with the release:

Upstream fix:

I've ported the patch to apply cleanly on top of all the other patches that are in the current ubuntu package, I'll attach it to this bug.

Simple use testing of the change shows it works as expected to me. MRU algorithim used when splits are not aligned, otherwise, override with directional switching.

If there is a better format for the patch, or if I should modify a source tree somewhere, please let me know.
