This patch adds a new command, move-pane. It is a wafer-thin wrapper
around the implementation of join-pane and simply removes the
restriction that source and target must belong to different windows.
In order for move-pane to be complete, join-pane gets a -b argument
that says to place the source before the target (left of for a
vertical split or on top for a horizontal split). A handful of stray
spaces that my editor removed are also included in this diff.
