Add Hashie::Extensions::Mash::RequiredKeys

Addresses #453, which asks for a way to have required properties
(like Dash) on a Mash that still allows arbitrary, undeclared keys
to be assigned (unlike Dash, which only allows pre-declared
properties).

Adds a new opt-in mixin, Hashie::Extensions::Mash::RequiredKeys,
that lets you declare required_keys on a Mash subclass. Missing (or
explicitly nil) required keys raise an ArgumentError at construction
time, listing all missing keys. Required keys are inherited by
subclasses and can be extended further in a subclass without
affecting the superclass's list.
