FFe update to 1.8

Developers from Amarok have requested we update to taglib 1.8.

TagLib 1.8 (Sep 6, 2012)
==============================

1.8:

 * Added support for OWNE ID3 frames.
 * Changed key validation in the new PropertyMap API.
 * ID3v1::Tag::setStringHandler will no londer delete the previous handler,
   the caller is responsible for this.
 * File objects will also no longer delete the passed IOStream objects. It
   should be done in the caller code after the File object is no longer
   used.
 * Added ID3v2::Tag::setLatin1StringHandler for custom handling of
   latin1-encoded text in ID3v2 frames.
 * Fixed validation of ID3v2 frame IDs (IDs with '0' were ignored).

1.8 BETA:

 * New API for accessing tags by name.
 * New abstract I/O stream layer to allow custom I/O handlers.
 * Support for writing ID3v2.3 tags.
 * Support for various module file formats (MOD, S3M, IT, XM).
 * Support for MP4 and ASF is now enabled by default.
 * Started using atomic int operations for reference counting.
 * Added methods for checking if WMA and MP4 files are DRM-protected.
 * Added taglib_free to the C bindings.
 * New method to allow removing pictures from FLAC files.
 * Support for reading audio properties from ALAC and Musepack SV8 files.
 * Added replay-gain information to Musepack audio properties.
 * Support for APEv2 binary tags.
 * Many AudioProperties subclasses now provide information about the total number of samples.
 * Various small bug fixes.
