Global theme for color scales

[JanPalasek]

Can we have a global theme for colour and fill scales? I would like set up colour and fill when I set up my global theme and override the default palettes for all plots. Like matplotlib has a color cycler, only here I would set up variants for continuous, discrete etc.

Perhaps you could wrap plot creation in a function that gives you a plot with all the scales you like?
I remember there being some warnings about unused color/fill scales though?
