Expose API that takes array of webpack configs

[anilanar]

Assume I have an array of unrelated, handcrafted webpack configurations. I would like to run them in parallel using parallel-webpack node.js API. For example if run function took an array of configs instead of config paths, it would somewhat work for me.

My proposal is to have a lower level API for running array of configs that is reused by the actual run function that takes config path.

An array of config paths or of config objects? The latter is not possible, see also #45.

Fair enough.
