Remove deref trait abuse

[ErnWong]

E.g.

crystalorb/src/timestamp.rs

Lines 261 to 272 in 6159018

	impl<T> Deref for Timestamped<T> {
	type Target = T;
	fn deref(&self) -> &Self::Target {
	&self.inner
	}
	}
	impl<T> DerefMut for Timestamped<T> {
	fn deref_mut(&mut self) -> &mut Self::Target {
	&mut self.inner
	}
	}

There are probably other cases.

Is there a reasoning for it?
(besides it is seen as bad practice)

[ErnWong]

Not really. It's not really blocking any particular use-case or causing any headaches (yet), but it might be good to get the semantics "right".
