Add tmux to the default yum repos
tmux is a terminal multiplexer a la screen, however contains quite a few features that the screen package does not support natively (such as vertical splits).
tmux is additionally in the default package lists for apt, so there is precedent for including it (why yum doesn't by default is a constant pain point for me).
More information about tmux is at http://tmux.sourceforge.net/
It would be very nice to have tmux in the default yum repos
It is now on https://github.com/tmux/tmux
