mentioned python 2.7, improved some text
renamed splitprefix to splitpart, added some tags, filters and replaces
version 0.1.14

catched IOError when loading/saving metadata to not to stop the whole script when running into erroneous albums
using longest common substr as a/artist if there is more then one (some could have 'feat. xyz' appended)
split before filtering, basetags of tags splitted by seperators gets thrown away
fixed bug with albumartists from mp3s
