[Gnuplot-py-users] Patch for mouse support (gnuplot.py 1.7)

Hi all,

here's the promised patch to make Gnuplot properly support mouse.  Please note 
that I only have access to linux boxes, so this hasn't been tested under any 
other platform.  I have, however, tried to make it portable by using only 
python code and no system commands.

The Gnuplot() constructor now has a new keyword option, 'mouse'.  If not 
given, it will try to auto-detect mouse support and enable it if present.  You 
may want to disable it explicitly for batch processing of very large datasets, 
because the mouse disables fifos, so it will be slower.

I hope this is useful to some, and after review Michael may choose to include it.

Regards,

f
