Title: Changed GetYOffset to make CMods an MMods compensate for music rate.

Mad Matt, shakesoda, and I all seem to agree that CMods and MMods should compensate for music rate.
They do not compensate for the haste effect because the sudden change caused by hitting a transition down in haste causes visual dislocation.
