Catrope 8baf7a1df9 Add mutators in MetaList
Add .insertMeta() and .removeMeta() methods to insert and remove
metadata through the meta list. For convenience, there is also a
.remove() method in MetaItem that wraps around removeMeta().

Also rename insertItem() and removeItem() to addInsertedItem() and
deleteRemovedItem() to avoid confusion, and make the MetaList
constructor take a dm.Surface rather than a document so we can call
change().
