Rugged::ReferenceCollection#update

Set the target of a reference. If +ref+ is a direct reference,
the new target must be a +String+ representing a SHA1 OID.

If +reference+ is symbolic, the new target must be a +String+ with
the name of another reference.

The original reference is unaltered; a new reference object is
returned with the new target, and the changes are persisted to
disk.

  r1.type #=> :symbolic
  references.update(r1, "refs/heads/master") #=> <Reference>

  r2.type #=> :direct
  references.update(r2, "de5ba987198bcf2518885f0fc1350e5172cded78") #=> <Reference>
