libtagedit and libtagedit-python 1.0b1 released

ibtagedit provides an easy to use interface for accessing ogg comments and ID3V2 tags from C++ or Python code. This is the first beta release of libtagedit on its way to 1.0.
The APIs of both libraries have undergone last modifications and are now frozen. The build system has been enhanced and clearified.
The id3Tag class was speed up by using code taken from mpg123 to determine bitrate and length of mp3 files, so that the file needn't to be read wholly each time.
