7abbe137b7 ArrayInquirer to correctly find symbols or strings
The problem existed where if your ArrayInquirer values were
strings but you checked them using any? with a symbol, it would
not find the value. Now it will correctly check whether both
the String form or the Symbol form are included in the Array.

c64b99ecc9 Add ActiveSupport::ArrayInquirer and Array#inquiry
Wrapping an array in an `ArrayInquirer` gives a friendlier way to check its
string-like contents. For example, `request.variant` returns an `ArrayInquirer`
object. To check a request's variants, you can call:

    request.variant.phone?
    request.variant.any?(:phone, :tablet)

...instead of:

    request.variant.include?(:phone)
    request.variant.any? { |v| v.in?([:phone, :tablet]) }

`Array#inquiry` is a shortcut for wrapping the receiving array in an
`ArrayInquirer`:

    pets = [:cat, :dog]
    pets.cat?    # => true
    pets.ferret? # => false
    pets.any?(:cat, :ferret} # => true
