Add '--simple-prompt' argument for sage

[mmmm1998]

IPython accepts a --simple-prompt argument, changing the input handler from prompt_toolkit to raw_input.

It would be very useful if Sage could pass this argument to IPython,
as it does with -gthread, -qthread, -q4thread, -wthread and -pylab,
because in Cantor, a front-end program for mathematical packages,
the Sage backend is now broken and that would fix it.

It would be nice to fix the Sage backend for Cantor!
