Fix playlist resume and SIMPLE-ARRAY pathname errors

- Add *resumed-from-saved-state* flag to prevent scheduler's db:connected
  trigger from overwriting resumed playlist position with full playlist
- Use sb-ext:parse-native-namestring in play-file to prevent SBCL from
  interpreting brackets in directory names (e.g. [WEB FLAC]) as wildcard
  patterns, which caused non-simple-string pathname components that broke
  cl-flac's CFFI calls
