auto merge of #2520 : saneyuki/servo/mut, r=Ms2ger

Related #2514

- This removes needless `&mut self`s from some DOM type method simply.
- This doesn't include some DOM Types which have basis method called from other types (e.g. `Element`). We still have to need to open their changes.
- This does not include to remove an implicit `deref_mut()`.
