1.0 to 1.1

* Added ID3v2.2 support (previous support was for ID3v2.3 and ID3v2.4) since iTunes
  seems to still use this very old version of the ID3v2 standard
* Fixed an API bug in MPEG::File that made it difficult to override the default
  frame factory
* Make it possible to override the default string handler for ID3v1 tags.  This
  makes it possible for applications to provide decoders that work with something
  other than ISO-8859-1 ID3v1 tags
* Switch from passing around a bool indicating whether to use synch-safe ints or
  not and pass the ID3v2 revion number.  This is more flexible and general purpose
* Optimizations in the toolkit that make several ByteVector operations faster (and
  speeds up tag parsing and rendering by about 20%)
* Fixed rendering of UTF-16 in ID3v2 tags
* Added FLAC support to the C API
