ns-unmap doesn't work on refers from cljs.core

Description

In ClojureScript, using ns-unmap on a symbol from cljs.core doesn't exclude it from the current namespace. Note that both a function and a macro still exist, even after unmapping:

This differs from the behavior of Clojure's ns-unmap. Note the appropriate errors when attempting to use unmapped symbols:

Somehow ClojureScript's ns-unmap needs to add the symbol to the current namespace's :excludes set. Note that the def special form does this already (after it displays a warning).

We have two solutions. 0001 extends the ns form's :merge behavior to support :excludes, and then uses this in ns-unmap. If the enhancement to ns isn't wanted, patch 0002 changes ns-unmap to update :excludes directly.
