Better wall-generating algorithm

v1 algorithm

The main complaint about v1 of aMaze was that the wall generation was too random and the mazes didn't look like real mazes. For example:

v2 algorithm

For v2, I implemented the "real" wall-generating algorithm, which creates mazes that look like this:

As you can see, the path to the end is not as straight-forward (read: down-and-right) as before. The paths you need to navigate are more interesting and more involved, with several paths going to the left and/or up.

This allows for mazes to be smaller, but still interesting to play. Because of the smaller dimensions and smarter wall-generating algorithm, you now have only 3 (down from 5 before) bombs at your disposal. Use them wisely :)

The scoring system has been slightly tuned for this new version. Time consumption is three times as costly as before, and the expected scores are much lower — anything over 700 points is considered amaz(e)ing.
