Make a recipe for PyQwt. Sadly this isn't easy.

The PyQt4 recipe in dizzy isn't 100%, but the one in master should be.

There is also a long term support issue with PyQwt and qt5, so it sounds
like we need to figure out how to replace Qwt eventually. Tom R. knows
the details.

PyQWT has refused to move to QWT6, so it's still stuck on QWT5's API. The good thing is that this actually interacts fine with QWT6 for what little we use PyQWT for, but the installation process for PyQWT is awkward (at best, most would say awful). We have this issue in OE and OS X macports right now.

We're talking about how to remove the dependency and replace it with something more usable and less likely to fall apart.
