Remove monkey patch on Enumerable (#71)

* Remove monkey patch on Enumerable

Instead of monkey-patching Enumerable to get some
methods we want on to arrays, we can instantiate
our own `BoxrCollection` object which behaves like
an Array. This is preferrable to monkey-patching
because we're not polluting the namespace of other
objects in our app which might use the Enumerable module.

* Bump version to 1.5.1
