Subject: Add resize-pane -Z to temporary zoom the active pane to occupy the
 full window or unzoom (restored to the normal layout) if it already zoomed,
 bound to C-b z by default. The pane is unzoomed on pretty much any excuse
 whatsoever.

We considered making this a new layout but the requirements are quite
different from layouts so decided it is better as a special case. Each
current layout cell is saved, a temporary one-cell layout generated and
all except the active pane set to NULL.

Prompted by suggestions and scripts from several. Thanks to Aaron Jensen
and Thiago Padilha for testing an earlier version.
