Convert the spellchecker and associated messages and functions to use string16

for words instead of wstring. I also changed some places where it converted the
word to a string to do that conversion at the last possible second before
giving it to Hunspell (since this conversion isn't needed for Mac).

TEST=Covered by unit tests
BUG=none
