Comparisons were always happening with lowercase version of the typed
word, which wouldn't match the uppercase word in the dictionary, so it
became an unrecognized word when typed in full. Highlight was then going
to the next word in the list.
Fix compares the lowercase and uppercase versions of the word for
validity.
Makes the user/contacts dictionary lookup faster. This is necessary because
there's more in these dictionaries now and it's written in Java.
Fix an auto-caps issue when moving the cursor. And do it a little lazily.
Fixed a bug that was causing user dictionary words to get a much
higher weightage than the main dictionary.
If the number of keys picked from proximity is too large, prune out
the subtree. Otherwise you get vastly unrelated suggestions.
Fix a bug introduced with the missing_chars checkin.
