Change from dbfile to dbdir, dbfile is now dbdir/dbfile

- add autosave 1 minute after change is made to db 1 minute
- improved gapless playback (used to run some code 10 times a second for gapless playback, is now event driven)
- saving now moves the previous file to dbfile-[UNIX-TIMESTAMP] in case something goes wrong when saving the new dbfile.
