This gets the number of songs that are locked for any reason.
I wonder why the unlocked songs functions say that songs locked
by unlock entries are counted there, but fair enough.
SetPreferredSongs(string) and SetPreferredCourses(string)
The files have to be named "SongManager <name>.txt"
Example: SONGMAN:SetPreferredSongs("mysongs.txt")
calls the file "SongManager mysongs.txt"
Metric added, [MusicWheel]::HideSections, will restrict showing one group at time, it you want to see the other groups use the next/prev group code, defaulted to "false"
Also group changing is allowed via gamebuttons in case of those who wants to take advantage of the codedetector too, "false" as default
SongManager::GetSongGroupByIndex, gets groups by index (helpful in Jump to group functions, thanks to juanelote for this too).
