[TYPO3-ect] lib/div: some common initialization before any action

[Alexey Boriskin]

I am writing an extension based on lib/div framework. It's a pleasure :)
But I have a feature request.
I need to create some commonly used objects, for example, object that 
manage user rights which should be accessible in any action of my 
conroller. I cannot extend constuctor of controller because my 'rights' 
object want to use configurations sub-object of a controller, but it is 
not yet created.

So, my proposal is to define a method of tx_lib_controller, that should 
be called before any action.
