[sciurius]

Sorting has ondergone many improvements since the initial implementation.
As it is right now, I think it would make more sense to consider alphabetical ordering to be really alphabetic, i.e. ignore any non-alphabetic characters from the sort.
This is often called "dictionary order".
Ignoring non-alpha should be applied to the titles only, so the sorttitle can still be used to override the order of particular songs.
