gui.c: Improve description of signal task.

The comment to the main() function of para_gui contains a short
description of all tasks which are created on startup. The description
of the signal task was somewhat outdated because it referred to
SIGWINCH, which is not responsible for the handling of terminal size
changes any more.

This patch removes the outdated part from the comment and adds an
explanation of the action on SIGUSR1.
