Exceptions while typing names in a custom taxonomy

[Adam Winer]

"It happens when I'm adding records, as I type the species name. Certain letters at he beginning of the species names seem to trigger it; recently L and P. If I dismiss the error message and keep typing, it adds the letters I type before the letter already typed, so I try to type 'pale' and get 'alep'.

This is all when I'm using my own taxonomy of moths and butterflies of the British Isles. I think it's properly formatted but I include it so you can check."

Buried the problem in d7ddd20a. I still do not see why this is happening; but presumably the code in Scorer.StableOrdering is less clever than I thought it is.

[Adam Winer]

I think the issue revolves around alternate names. The "stable ordering" codepath is ignored for those.

Resolve Issue #368, for real (I hope): support proper snapshotting of ordering in all IndexerPanel cases
