Inferno colormap not working

[jrwrigh]

The inferno colormap isn't working for some reason. If you load the file and select it as a colormap option, it just leaves the previous colormap on the contour plot. If you then change a setting in the contour while it is selected, it will just display a fully white colormap.

Quick fix is to right click "Graphics" on the tree, to go "Colormaps...":

Go to "Edit":

Then, with "Inferno" set as the Currently Defined colormap, save a new colormap as "inferno2".

The "inferno2" colormap then works completely fine. Not sure why this is happening, as obviously some part of the colormap is working fine since a simple rename is fixing the issue.

Problem possibly fixed by #4. Still need to verify.
