change bundle.js -> ramdaRepl.js; add authors to package.json

[buzzdecafe]

A few changes:

1. Rename bundle.* to ramdaRepl.* to avoid collisions;
2. Add "contributors" field to package.json
3. add build task to package.json that wraps up css, js, and minify steps

Sorry, only just saw this - it's been a wacky week. I'll take a look this evening 👍

no worries, no rush.

This looks good to me.

I'm conscious that Try Ramda references bundle.js and bundle.css:

https://github.com/ramda/ramda.github.io/blob/master/repl/index.html#L56

I think we would want to simultaneously merge this and update Try Ramda at the same time to use the new filenames (I'm not sure how long the old ones will be available on the CDN). What do you think?

sounds good to me, i will try to find some time to raise a pr on the docs repo
