Cleaning-up nearlib for release (take 1) (near#452)

* Re-hash nearlib imports so that only one `require` is needed
* Enable eslint and apply auto fixes
* Apply manual ESLint fixes
* Rename exports.js -> browser-exports.js
* Add dev subpackage in browser library (based on https://github.com/nearprotocol/NEARStudio/pull/70/files)
* Add dist/ to repo to allow serving via jsDelivr
* window.nearLib -> window.nearlib
* nearlib.dev.initDefault -> nearlib.dev.connect
* Create user if needed when connecting to near in dev env
* Remove superagent dependency
