Statusbar

A statusbar can be shown at the foot of a form.

There are 3 statusbar commands:

sbar n;	n is number of panes in the statusbar
sbarshow b;	b is 0 to hide, 1 to show (default)
sbarset id width text;	a width of -1 leaves at current value

The first pane is special. Its width is variable and takes up what is left. It does not have a border. It can be used to display help text for menu and toolbar items.
