Spelling inconsistency: Clonable and Cloneable

[octurion]

std::vec::MutableCloneableVector (http://static.rust-lang.org/doc/master/std/vec/trait.MutableCloneableVector.html) and std::iter::ClonableIterator (http://static.rust-lang.org/doc/master/std/iter/trait.ClonableIterator.html) do not have a consistent spelling for Clon(e)able.

Nomnating.

Looks like java uses Cloneable and google autocorrects to Cloneable, so sounds like Cloneable is the way to go here.
