optional method for controlling public access

[CodeBlastr]

Please see the usage notes in the comments to see how this is a new optional method allows users to control public or guest access from the permissions.php config file. The benefit is that it allows all permissions to be controlled from a single place - including public permissions, as opposed to having some permissions in the individual controllers (eg. $this->Auth->allow('someAction')) and some permissions in the config file.

I see... yes, this could be a good improvement for people who wants to define all rules in the same place.
Instead of using '*' or 'public' I would add a new rule option like

 [
    'public' => true,
    'controller' => ['Pages'],
    'action' => ['other', 'display'],    
]];

Then we could match the controller in the component initialize to configure the controller's Auth->allow() with the extracted actions.

NOTE: Please send feature contributions to develop branch instead of master (I'll close this one and look forward to see your new PR)

Thanks!
