Sanitize filenames: replace spaces/punctuation with underscores

Browse source 
Replace all non-word characters (spaces, punctuation, brackets, etc.)
with underscores in track titles, album names and artist names.
Collapse consecutive underscores to one, strip leading/trailing ones.
Umlauts (ä, ö, ü, ß) and digits are preserved.

Also use underscore instead of space between track number and title.
