Title: when creating sort name ignore non-alphanumeric and convert '_' to space

This is to address issue #24. When creating a sort name it replaces all Unicode characters that are not letters or numbers with spaces and then trims. This accounts for artists with punctuation in their name. It may be worth replacing umlauted and other special versions with their plain ascii version. I don't know enough about other languages to say if that's a reasonable behavior.
