Update 1.3 — Glass Steam update #986635

This update entails the changes listed below. We've been play-testing these changes for several weeks and we feel that they make the game more fun and enjoyable. We hope that you feel the same. Marble friction and bounciness have been reduced in order to make marble motion more fluid. The procedural generation algorithm has been modified to make flat and downward sections equally likely to occur (previously, flat sections implicitly appeared more frequently than downward sections). There are two side effects of this change: Tracks are now shorter since downward sections appear more often. The amount of time required to complete a track has been reduced by approximately 50%. A given seed will produce a different track than it did before the update.
