account for size-change when rotating between landscape and portrait modes
When the control panel is opened for the first time, a table is
generated with a number of columns based on screen width. If the
screen is subsequently rotated, the column number is no longer
correct. In addition, the scrolled window holding the table needs to
be resized so that it fits on the screen.
This patch adds a size-changed callback that recomputes the number of
columns and resizes the table and its containing window.
