Restore (and improve) support for ocamlnat. It's now possible to use #use "down.top" regardless. So if you don't have fancy stuff in your .config/ocaml/init.ml it will work equally with ocaml and ocamlnat.
Incidentally we no longer need to detect the presence of ocamlnat which solves #33 (Thanks to Jacques-Henri Jourdan for the report).
down.top in ocaml's library directoy. OCAML_TOPLEVEL_PATH is supported since 4.08 and opam env now sets it correctly. With that the file we install the toplevel library directory should be enough for #use "down.top" to work.%%LIBDIR%% substitution in order to deal with spaces (#38, #41). Thanks to Nicolás Ojeda Bär and Antonin Décimo for reporting.opam var instead of opam config var.C-t): allow cursor to be on the whitespace or non-identifier characters after the identifier. Thanks to Zeng Li.First release.
