Comment 8 for bug 1791280

@Seth, any rescue that does not include the imported schematics cache library carries a high probability of not being correct which is almost as bad as not being rescued at all. I cannot think of any other way to do this accurately. This is why I added the warning dialog because I could not think of a better way to do this. I wonder if it's worth the effort. Once the new schematic file formats are implemented, all of the mapping and rescuing issues go away. I suppose you can try to remap using the current projects library table but your mileage may vary greatly.
