Title: --pylab option added to isympy session.

The plots are now non-blocking. This does not completely solve
the problem with plotting, but makes it better.

I have tested in ipython versions >= 0.11. Ipython is not working for me for versions <0.11.
Can somebody test it on versions <=0.11?
Thanks.
