Softened the metadata-editor behavior to not deliberately delete additional, valid frames which are stored in mp3-files.

Stashed commit of the following:

e54bcd2f058d186c2c919a84152ed5e8526047fc
Fixed bugs/comments from John Maguire

01c71c4c67be44dd6889498abc323a6d2d20dd99
Added description "Clementine editor" to new created lyrics frames.

70dfa0d1f177523ff897985ae022979cd052a6ed
Updated the SetTextFrame method as well:
Existing frames are cached and only the first frame (which is actually shown in the metadata editor) will be updated.
Prevents the cruel deletion of all other existing frames in a well defined mp3-file.

dfddf76eda417442c8c168eb8868038b0675cb10
Updated behavior of metadata-editor concerning lyrics (might follow for other id3v2-tag properties):
Existing further frames in the tags are not deleted but cached so only the true changes by the metadata-editor are applied on the edited frame.
Further frames in the metadata are preserved.
