Reusable methods for public and admin controllers

Hello @robert Peake,

there are some really useful methods that are only available for Admin controllers. They are located at MvcAdminController class.
For example:

• create_or_save()
• flash()
• verify_id_param()
• edit()
• delete()
• and so on …

I think it will be really useful this methods to be reusable for both controllers – public and admin. Maybe they should be relocated at MvcController class (possibly there is a need of a small refactoring).

Greetings,
Jordan
