Display multiple Colour space numbers

[mikemeister_admin]

In the right hand column of the curve screen only one colour space sample readout is displayed, e.g actual, RGB,Lab etc.  Being able to choose see the values of the current sample in multiple spaces would make it easier to identify possible problems, casts etc.  As Dan M says ever pic has 10 channels.

This will also help in deciding which space to apply curves.

Excellent suggestion, Brian.  Although you are not the first to suggest this, you have provided some additional convincing reasons to add the feature.  Thanks.
