Rely on index.js instead of index.json

[rgbkrk]

As noted in Qix-/color#69, this package currently requires webpack and react-native users to have to do custom things to require this package in their applications, due to the top level module coming straight from .json. This switches over to a simple index.js file.

I ❤️ color, so I'd love to keep using it now that I'm using webpack.

Thanks for shipping this!

Not sure that deliverying this as a patch was a good idea (eg: someone can hardcode the reference to the json for some "you don't want to know" reason).
Looks like a breaking change.

Looks like a breaking change.

That's a fair assessment. If the exported interface were changed, I would say this would be a major version change. Since this changes the implementation and not the exported interface on a require, this would adhere to a minor version bump, which is what @dfcreative did - 1.1.0 had this change. 1.1.1 was a tiny fix to that. I should have mentioned that in the other issue, I provided 1.1.1 to let others know what to pin.

Instead of me squabbling about whether or not someone did a "you don't want to know" hardcoded dependency on a file structure without pinning the version, I dug around to see uses of the package:

All the libraries that rely on color-name do a direct require:

• https://github.com/dfcreative/color-parse/blob/239286bc440b50c7c34f742b4b8b555198fcdb6e/index.js#L8

There are only two other repos with direct reference to color-name it's part of an npm shrinkwrap:

• https://github.com/camiriveron/gossip-tweet/blob/10ad44971cf3d3ee2c89f9b8fa0904b39abb52f1/npm-shrinkwrap.json#L2445

All this being said, after digging through previous issues, if we want index.json available in the published package, this can go in the package.json by writing out the json directly as a prepublish step:

diff --git a/package.json b/package.json
index 52ec3b1..f1a7001 100644
--- a/package.json
+++ b/package.json

No fancy dependencies there and it runs before a publish, based on how npm works as a build tool.
