Use modularized imports for lodash

[christoph-buente]

There is a version of lodash, that does not need to be prebuilt. You can easily require the submodul you need in your code. And then browserify will filter out unrequired code.
https://www.npmjs.com/browse/keyword/lodash-modularized

For example isArray: https://www.npmjs.com/package/lodash.isarray

That would make it much easier to use snowplow itself as an npm module.

Alexander Dean (@alexanderdean) should be fine, I've used a module with the work I'm doing with global contexts, though it seems to make concat complain:
gruntjs/grunt#662

It should be fixable, but still trying to find a workaround.
