Removed long deprecated and obscure CloneableCo...

Removed long deprecated and obscure CloneableCollection. Discovered
we have a scala.collection.mutable.Cloneable which does not extend
java.lang.Cloneable, which is why Array is not considered cloneable.
That seems wrong, but to be conservative I gave Array the Cloneable
interface without altering the scala trait.

Also, if @serializable is deprecated in favor of Serializable,
should not @cloneable be deprecated analogously? Closes #4307, and a
commit-question review by rytz.
