Support for :all

[alexr17]

CanCanCan has a nice shortcut for managing all models: can :manage, :all and it would be great if this gem had that too, or something similar. I noticed a quick fix that would allow something like this to work:
can :read, ApplicationRecord

In permission.rb:

def matches_subject?(subject)
    subject == @subject || subject.class <= @subject
end

Adding .class onto the end of @subject allows the second condition to work successfully. Otherwise, it evaluates to nil.

def matches_subject?(subject)
    subject == @subject || subject.class <= @subject.class
end

I'm going to close this because it can be monkey patched, and my solution actually introduces a different bug.
