Create DT badges for readme.md

[Bartvds]

Standard badge for readme's so a JavaScript project can show it has typings on DT (like travis, gemnasium, built-with-grunt etc).

As per #1951 (comment):

@basarat We might start sending PRs to other repo owners README files telling them their repo name on tsd / DT so that typescript users can see that the project has a definition file.

The link can go to like:

1. definition file on repos
2. content page on definitelytyped.org
3. page on www.tsdpm.com
4. ..?

Maybe we should setup a redirect script so we can update the destination format (yes)

For graphic:

We can start with a simple design (svg/png), but for a dynamic version we could add some fields we could try to extract:

1. official vs user-supplied
2. freshness (updates)
3. traffic (collect from NuGet + TSD)
4. version info (from header or meta)
5. version match (with package.json)
6. has test
7. has globalvar
8. has external module
9. on npm, bower etc
10. test coverage
11. ..?

If someone rigs it 😎

This sounds really awesome, guys!

I think it will be really awesome to make it enticing for JS library developers to stay in sync, and maybe be flattered by the community support for their projects.

Mmm hmm.. So, uh, how you want to rig it? 😏 💅

Very cool! Now we really need someone with a skill for design.

This is a brilliant idea!

I created a new repo for the badges: https://github.com/DefinitelyTyped/badges

To start exploring this I put some existing badges in a file (please add more if you know them)

If this interests you please Watch that repo.

I'll close this issue, please move the discussion to the new repo.
