Rename to "content-address*ing* derivation"

Browse source 
"content-address*ed*" derivation is misleading because all derivations
are *themselves* content-addressed. What may or may not be
content-addressed is not derivation itself, but the *output* of the
derivation.

The outputs are not *part* of the derivation (for then the derivation
wouldn't be complete before we built it) but rather separate entities
produced by the derivation.

"content-adddress*ed*" is not correctly because it can only describe
what the derivation *is*, and that is not what we are trying to do.

"content-address*ing*" is correct because it describes what the
derivation *does* --- it produces content-addressed data.
