Reformat package.json for npm

[jiribenes]

Motivation

npm version major/minor/patch can change the version of the currently developed npm package:

• by bumping major/minor/patch in package.json
• making a commit
• and a git tag

... which makes it very nice to use to make a deploy using a single command.

Unfortunately, it reformats the package.json file into a more standard version. It's still 4 spaces, but a bit more verbose.
I think the trade-off is worth it here, just to make releasing a bit easier.

Description

I ran npm version patch and only selectively added the things that do not change the version, thus making the diff smaller for an actual release.
