Wishlist: EasyTag should be able to edit additional tags

[Giannis Servetas <johnservetas yahoo gr>]

Right now in version 2.1.7 (Debian Testing) the tags available fro 
EasyTag to edit, are Title, Artist, Album Artist, Album, CD, Year, 
Track, Gerne, Comment, Composer, Orig. Artist, Copyright, URL, Encoded by.

Anyway, as known ID3v2 tags suport much more tags, like Lyricist, 
Language, Orig. Performer, Soloist, Publisher and many many others.

Is it difficult to integrate full support to all these tags? Is it 
something planed? In which version?

Thanks!
