Title: Isympy options

I added a -D option to isympy, which enables debugging output (used extensively by Tom's new integration code, for example). I also made the docstring of the file print with --help, and made --version/-v work as expected (print the sympy version).

Please see the XXX comments in the code. Some of these are done in a less than ideal way.
