This reverts commit 963a2092efefb62f8f8b1216f0a7d05bbebb884d.
I still say we should use "colour" for consistency, but that change should not be part of this branch.
CURA-333
I know "colour" is the more correct spelling, but Qt uses the spelling "color" and we have already adopted that spelling in a number of places.
CURA-333
There used to be an extruder object from which we could ask these properties. But now we have a container stack in its place, so we need to get the properties in a slightly different way.

This requires some trickery of initialising the extruder manager before the machine manager is initialised, so that it properly listens to global container stack changes.

The fix is likely not what was intended by the author of the offending code (and does not seem to be functional), but at least it fixes the hard crash outlined in CURA-1666
The result of the function was None, but I don't need None to be called whenever extruders changed. I need the function itself to be called.

Hasn't been tested much because there is no display for this in the front-end yet. It needs a setting data type to go with in order to display it. This model is for the drop-down boxes to select an extruder to print, for instance, the support with.
