Decrease bundle size

don't inject http,https,os,utils polyfills. they are required only inside condition isNodeEnv, so we are safe to remove them from the browser bundle

extract from the heavy url-parse package only what we need

@n400 there are some more improvements and investigations we can do. for example, replace fn-annotate package with our own implementation will save about 0.6kb (for minified version) as well as review query.js which currently takes 41% of bundle size.

one thing more, we probably could extract streaming feature to separate package, so users who don't need this feature will install only fauna core features
