MediaLibrary 0.10.1

This version fixes some potential crashes or database corruption:
- An external audio file with multiple tracks would cause a constraint
  violation. This is worked around for now and is properly handled in
- When forcing a playlist rescan, the internal counters were not reset,
  which would cause them to grow exponentially each time a rescan was
  performed. They are now properly reset to 0

In addition, a few minor fixes and improvements:
- Guessing an unknonwn media type based on its extension was done in a
  case sensitive way. Now it will be performed in a case insensitive way
- .far .669 and .mtm extensions are now recognized
