Update to 1.1.

Changes:

Version 1.1
 * The intensity of rain and storm is configurable now. New options:
   -rain <0-10> and -storm <0-10> (the old yes-or-no variants are \ 
deprecated).
 * The viscosity of the fluid is no longer a constant (without any speed
   loss). New option: -viscosity <1-5>
 * The rain feature no longer prevents from the idle mode: just obscure by
   other windows, but don't give -nww.
 * Bugfix: On 64-bit x86, xdesktopwaves now even compiles with gcc 3.4.
 * Bugfix: Fixed arithmetic exception on systems with a small RAND_MAX.
 * Bugfix: If -stippled, clear window at initialization.
 * Optimization/Bugfix: The color palette is reduced to have only different
   colors. This can spare about 10% of the rectangles sent to the server,
   if the display depth is 16-bit.
 * Optimization: Treatment of minimum range of out-of-date canvas rows. This
   spares up to 50% client CPU cycles when there are just very few waves
   (shortly before entering idle mode).
