Auto add new words to the user dictionary.

First pass at automatically adding new words that the user types and deliberately
accepts.
After typing the word 4 times, the word gets promoted to being valid.
After typing the word 7 times, the word gets added into the UserDictionary and can
be removed from the UserDictionary Settings UI.

Also add a second row of symbols to the period popup.
