Use lodash instead of mout

[koresar]

Since lodash v3.0 you can require('lodash/object/merge') exactly the same way as we do with mout.

Lodash is a bit faster, a bit smaller, uses a bit less memory.

Additionally, lodash has _.matches function which could be handy implementing #50.

Also lodash is under active development, have better online docs and JSDoc.

Absolutely agreed, and IMO should be a good thing to add to 2.0.

Implemented with #63 and #60.
