Allow searching for words with apostrophes.

Browse Source 
Previously, because apostrophes were 'banned' characters, searching for
them wouldn't work. That meant you couldn't find words like "I'm". Now
we just replace the apostrophe with a space and things "just work"
because of the nature of SQLite tokenization and prefix queries.
