Docstring / parameter consistency for swap!, reset!, swap-vals!, and reset-vals!

In Clojure, the parameter and docstring for swap!, swap-vals!, reset!, and reset-vals! consistently refer to atom and newval, but in ClojureScript this is not true.

In ClojureScript, a is used as a parameter name instead of atom, and for the reset functions, the parameter is named new-value, while the docstring refers to newval ( and in ClojureScript, there is one reference to the parameter as new-value in at the end of the reset! docstring).

Suggest changing the parameters and docstrings to be consistent, matching those in Clojure.
