More REPL-friendly 'ns macro

Description

The 'ns macro is not as dynamic as it could be.
For instance, the following line typed in a repl (ns a)(ns b (:require a)) currently (1.4, 1.3, etc.) fails with an exception because the (:require a) call tries to reach the filesystem for file a.clj or a__init.class.

The attached patch ( dynamic-ns-patch2.diff ) allows a successful call to (ns a) behave the same as a successful call to (require 'a), adding namespace a to the list of loaded-libs.

I see this has already been screened, but FWIW I tested the repl with this patch and the behavior works for me.
