[PATCH-3-5] speedup autocorrect database import ...

[Michael Meeks]

	Large autocorrect databases cause quite some slowness on first
keystroke for people; turns out we had quite a gratuitous N^2 on load
there involving some ICU collation goodness ;-)

	It's still not ideal to have a multi-second freeze, but at least it's
half the length it was ;-)

	Review appreciated,

	Thanks,

		Michael.
