Ensure all calls to contour have sorted levels

[zblz]

With these changes, all calls to plt.contourf have sorted levels (see matplotlib/matplotlib#5477 and matplotlib/matplotlib#5485). This allows to use corner in matplotlib > 1.5.0.

Fixes #65 and #68

Thanks Victor. Unfortunately this isn't quite right. For example, for the hist2d_filled test case in tests.py, this gives:

which is better, I agree, than it used to be but the final level should be transparent not black.

I'm happy to look into this but I won't have a chance for at least a week and possibly more so you should give it a try if you have time :-)

Thanks again for this contribution!

@dfm: I just realised that, and fixed it in 72bac6f! The colormap was being built in decreasing order.

I now get this:

Excellent! That looks better! Just add your name to corner.__contributors__ and I'll merge.

@dfm: Done!

edit: Also, I think this deserves a bugfix release, otherwise with matplotlib 1.5.1 out as stable reseale quite a lot of people will find bug #68

Thanks! I've pushed a new 1.0.1 release to pypi.
