- Part of the typechecking code was using the monomorphics subtyping function instead of the tallying (when checking the body of a function)
- The function Var.gen that was generating new versions of typed variable names was not properly incrementing its internal counter, thus generating the same name for two distinct variables.

Work around to load camlp4 when compiling the parser is rebuilt as a dependency of the standard library.

 - Properly check for unbound type variables in type definitions.

Improve the Float library and fix a bug in the dlink module (the computed path was not passed to Dynlink.loadfile).

Start refactoring sources and move all code that depends an external libraries and can be switched at runtime in the plugins/ directory.

(Clears the type and compile environment, the compilation unit table, the table of named types and reset to their default values).

Minor tweaks and add the file driver/cduceeditor_js_runtime.ml that was previously not added to the repository because of a buggy .gitignore entry.

One can pass the undocumented --allow-cduce-unsafe-ns to the compiler
to use these primitive directly.
