[Idea] Custom authentication through controller base class

[tim-vandecasteele]

Hi,

Before creating a pull request, I wanted to check if you would be willing to accept it.

I'm running a custom authentication scheme, so not using Devise, and I want to put pghero (which I think is great btw) behind something more complex than basic authentication.

I believe the mission control interface does this in a nice way, by being able to define the base class of the controller in Rails config.

See the documentation or the implementation.

If this works for you, I would implement it in the coming weeks.
