Subject: Install a txrlisp hard link.

* Makefile (LN): New variable. On platforms where
you can't hard link, this can be replaced with some
other command. Possibly "true" not to have the alternative
executable name created at all.
(HARDLINK): New macro.
(install): Use HARDLINK to create a link named txrlisp
pointing to the same file as txr in the destination
directory.

* txr.c (txr_main): If the executable ends with "lisp"
(or "lisp.exe" on Windows), then default the txr_lisp_p
variable to t, which has the effect as if --lisp had
been processed.

* txr.1: Documented.
