Few fixes in dune files. Prepare an opam branch that will be compatible both with menhir >= 20181006 and earlier versions.

nl_lexicon now restricts the non linear interpretation to the interpretation of -> and lambda at the abstract level. It is the user's responsability to have Lambda's and => in the lexicon and in the object signature when required. Fixes #12

Restrict the effects of nl_lexicon to de-linearization of abstract -> and abstract lambda only. Fixes #12

Dypgen dependeny removed. Dependencies to menhir added. Moved to 1.5.0 version. Compilation works and first tests (local grammars and scripts, and TAG2ACG grammars and scripts) are ok.
