remove HKT in typescript bindings, fix TS 2.4 support

[emmanueltouzery]

remove typescript binding bits which assume higher-kinded types support: those bits break with typescript 2.4. Fixes #144 the library now builds OK with typescript 2.4+.

It's a shame to lose this but that's the language we have. See my latest comment in #144.

@estaub suggested in #144 to keep the interfaces but just comment their contents, but I don't see the point. We can explain the interfaces in the documentation, no need to list them in the .d.ts files I guess.

I also noticed that it seems we don't anymore ship the generated files in git? That would mean two things:

1. the CONTRIBUTING.md is outdated because it suggests to run npm run publ
2. according to my understanding, it's now impossible for an application to depend on a git tag of monet, like this for instance "monet": "https://github.com/cwmyers/monet.js/tarball/575dafec572b7e01bc9071ee969a7f9771207964". That's a letdown because monet is not released very often. If that's true and you accept this PR, I suggest to release a new alpha quickly after pulling this PR so people depending on monet can migrate to TS 2.4 -- previously they could have done it by referring to a git tag, but now they could be stuck

It's rather painful regression… I'll try to figure out some less destructive solution. If I don't manage to deliver it within days, I'll approve and merge your PR.

Ad. 1 - you are right -- will fix it with release.
Ad. 2 - will do that as soon as some solution is merged.

Thanks for investigation and your work :)

sure. Do read what I wrote there:
#144 (comment)

specifically the solution that the fp-ts library is using. The author wrote a whole blog post on this issue!

[emmanueltouzery]

this PR is probably obsolete since monet appears to compile fine with recent typescript@next (future typescript 2.6) versions...
