Word phases

This solver does the following phases:

1. Look at all answer possibilities, and finds the word that has the most frequently used letters, given their positions.
2. When enough letters are found (3), switch to rating letters non-positionally. Also, do not give any score to letters already known.
3. Once 3 letters are found, it tries to eliminate remaining possible answers. For example, given ?atch is known, it finds a guess word that contains p, m, w for patch, match, and watch (ignoring catch and hatch because those letters are already found).
4. When only a couple words remain, just guess.
