Color change - handling Color Change data stored for different

Browse source 
printer configuration:

ss -> sm : Just apply the color changes of the original ss project at the active extruder.
ss -> mm : There are no tool changes stored. Ignore color changes, they are invalid because they are extruder non-specific.

sm -> ss : Apply tool changes as color changes (tool changes remember the target color), apply original color changes.
sm -> mm : Ignore both color changes and tool changes.

mm -> ss/sm : Ignore both color changes and tool changes.
