 * Saving StageStats that are affected by the note pattern is a little tricky:
 *
 * Stats are cumulative for course play.
 *
 * For regular songs, it doesn't matter how we do it; the pattern doesn't change
 * during play.
 *
 * The pattern changes during play in battle and course mode.  We want to include these
 * changes, so run stats for a song after the song finishes.
 *
 * If we fail, be sure to include the current song in stats, with the current modifier set.
 *
 * So:
 * 
 * 1. At the end of a song in any mode, pass or fail, add stats for that song (from m_Player).
 * 2. At the end of gameplay in course mode, add stats for any songs that weren't played,
 *    applying the modifiers the song would have been played with.  This doesn't include songs
 *    that were played but failed; that was done in #1.
