Added without_default_scope option

[westonganger]

I added an option to skip the default_scope. This makes the gem much more versatile and not susceptible to all the problems that come with default_scope.

Thank you @westonganger. I love this.

Is it possible to add a test?

[westonganger]

I have added a test for this.

[jhawthorn]

Awesome. Thanks.

Works thx. Had to move from 2.1 to current rails4 branch.

Hi, I could really use this feature, will a paranoia 2.2 with it included be released anytime soon?

FWIW, for others coming across this, here's how I monkey-patched it in, roughly, in the specific class where I needed it...

    acts_as_paranoid without_default_scope: true

  paranoia_spec = Gem.loaded_specs["paranoia"]
  if paranoia_spec.version < Gem::Version.new('2.2')
    default_scopes.delete_if do |scope|
      scope.source_location.first.start_with? paranoia_spec.full_gem_path
    end
    class << self; alias_method :without_deleted, :paranoia_scope end
  end
