0.3.1

CHANGES:

• Disable warning 69 (unused-field in record) for the private record
  generated by the bs.deriving attribute
  (#414)
• Disable warning 20 (ignored-extra-argument) when applying
  foo##fn arg1 arg2
  (#416):
  • in cases such as external x : < .. > Js.t = "", the typechecker doesn't
    know the arity of the function, even though Melange will emit an uncurried
    function call.
• Disable warning 61 (unboxable-type-in-prim-decl) in external declarations
  (#415):
  • Melange externals are substantially different from OCaml externals. This
    warning doesn't make sense in a JS runtime.
• melc: introduce --bs-module-name flag to specify the original file name for
  the current compilation unit
  (#413)
  • Dune's namespacing implementation generates modules such as
    lib__Original_name. Passing --bs-module-name original_name allows
    melange to issue correct import / require statements to the unmangled
    JS file names.
