Fix ProtoPalette::compare

Browse Source 
The function only stopped at the end of the *arrays*,
not of *their used portions*!
This could cause false negatives one way or the other.

This appears not to affect the palette packing, since the packing algorithm
deals with them efficiently; but it should speed up processing slightly,
and as the test changes show, it also improves the UX of palette packing
error messages!
