Updating package.

[Fazendaaa]

Hey, @misterhat. Thanks for this awesome package!

Due to Hacktoberfest 2018, I'm contributing to some packages that I use; yours is one of those.

I was going to only make TypeScript(TS) typings to your package, but since it was an old package I've decided to make some changes:

• Using promises instead of callbacks;
• Removing ALL packages dependencies, making it less likely to need to update it in a near future;
• Added a .npmignore;
• Rewriting in TS;
• Integrating linter standards;
• Setting git hooks with Husky;
• Using Webpack to handle file integration;
• Writing new and more comprehensive tests with Jest;
• Continuous Integrations (CI) with:
  • Travis CI
  • Codecov
  • Codeclimate
• Updating docs;
• Making use of typedoc to integrate with Github pages -- https://fazendaaa.github.io/omdb/;
• Linked typings file in your package.json -- making no need to submit to @types;

TODO:

[ ] If you decided to accept this PR, please be aware of modifying the README.md, a simple regex replacing all of Fazendaaa to misterhat gets the job done;
[ ] Create an account, if not existing, in all of the CI services -- they are free for Open Source projects;
[ ] Just go to your repo settings and activate the Github pages options.

That's it, thanks again and keep doing this awesome work :)
