The bin order changes upon Classifier training set reload

[dlogan]

Classify with 3-classes (I haven't tried more for this Issue). Let's say the Classes as displayed left-to-right are C1,C2,C3. Save training set, close and re-open CPA, reload training set, and then the displayed classes are (L-to-R)L C1,C3,C2. Once saved, the training set file header changes order too.

However this is not simply a display issue, at least as it stands now because ClassifyPixels in CP has an input of "class #", which the user presumes is left-to right, 0,1,2, etc, rather than 0,2,1.
