#56 OCaml parser for ctags

[Vincent Berthoux]

Here is the patch against CTags 5.7 to provide support for OCaml. Due to an extension clash with lisp on the ".ml", I've removed it from the lisp parser (as it was the last one, I hope it won't be a big trouble).

The parser output scope information and kind within the limits of it's possibilities.
