Remove Bolts dependency and related helper files (#223)

Based on discussions in #222 around how to handle the Bolts dependency, it was determined the best course of action is probably to remove the Bolts dependency entirely, including the small set of helper code that made use of it.

Since the helper code is not complex and can easily be added by developers to their own projects, it was agreed that the removal of the Bolts dependency outweighed the benefits of having these helper methods available by default.
