Add a unit test for Hunspell spellcheck

Add a unit test for Hunspell spellcheck

Chrome has been suggesting "Othello" for "hellllo" and "identically" for
"accidently" because the Chrome version in Hunspell assumed that dictionaries
contain at most one affix per entry. This CL adds a unit test that verifies
Hunspell no longer has this erroneous assumption.

LGTM - unless you feel inclined to actually create a new test case file for
hunspell stuff.

Grumble. This should technically test hunspell, not SpellCheck. (I know, we're
doing this a lot. Still, at some point I'd like hunspell checks)

I understand your concern and will take care of it when I have some free cycles.
