New slet macro.
* lisplib.c (place_set_entries): Add slet symbol to autoload
list for place.tl.
* share/txr/stdlib/place.tl (sys:r-s-let-expander): New
function.
(rlet): Replace body with call to sys:r-s-let-expander.
(slet): New macro.
* txr.1: Clarification and corrections in rlet description
and example. rlet will in fact handle the three-variable
rotation case because, since a is not a constant expression,
(rlet ((temp a)) ...) reduces to let.
Documented new slet.
