Subject: Avoid redundant redraws on resize

Use a global flag to record whether the terminal was resized instead of
redrawing everything each time a KEY_RESIZE is read.

Add some additional checks to help_write_pad() as invalid actions may be
passed now due to using signals instead of virtual key presses.
