Backport custom song support. Prefs are CustomSongsEnable, CustomSongsMaxCount, CustomSongsLoadTimeout, CustomSongsMaxSeconds, CustomSongsMaxMegabytes. Metrics are NumProfileSongGroupColors and the colors with it. Profile custom load function is passed PlayerNumber now. Stepmania must run as root to save USB profile scores. (#1470)
