Color Management Presets

Save your Color Management options as presets, for easy re-use.

It will pretty much every option in the Color Management panel, such as
the look, color settings, and so on. Except the curve points (have to
figure out how to do that nicely), good news is that in Blender 2.69+ you
can now copy/paste curves.
