0.2

0.2 will introduce some API changes to bring it more in line with its Clojure siblings and make certain operations more explicit (i.e. deep merging):

- [x] Rename `assocObj` to `deepMerge`, expose explicitly via `sprout.deepMerge(a, b)`
- [x] Let `assoc` and `dissoc` take an arbitrary amount of arguments
- [x] Remove `dissocObj` (API is confusing, use variadic `dissoc` for dissoc'ing multiple keys at the same time)
- [x] Update documentation
