Revisit version pin for prettytable

[phmccarty]

Looking at the history of the prettytable version pin (see #136 and #144) and checking that package's release history on PyPI, I don't see a release with version 7.

Was that version 7 release scrubbed from the PyPI history? If so, can the version pin be removed?

I have not tested ipython-sql with newer releases of prettytable, but I wanted to raise this question since the motivation for the version pin seems to be outdated.

Is the pinning to version 0.7.2 really necessary or could I update to a more recent version? Pinning to rather old versions is a bit problematic for packaging projects. Thanks!

this should be revised and ideally changed to remove pinning of version so anyone can install version of choice, or at least update to newer version
