Publish non-minified bundle and/or sourcemaps.

[jasonkarns]

With only the minified bundle published, it makes debugging the minified source rather difficult. I request that the published tarball include a non-minified bundle, such that we can debug a non-minified version of the library (or at least use our own minifier so that we can generate the corresponding source map).

At the very least, I would request that the sourcemap for the existing minified bundle be distributed alongside the bundle so we can at least debug with that. (preferably, both the sourcemap and non-minified bundle would be published so consumers can make their own choice.)

This is now addressed in the latest 2.0 release where we publish non-minified bundles to dist/optimizely.browser.umd.js
