[TYPO3-mvc] !!! Dependency Injection fixes

[Sebastian Kurfürst]

Hey,

I have just now refactored the Dependency Injection container; and
wanted to ask you if you could thoroughly test these changes.

This refactoring has now paved the road to "initializeObject()", which
is a method which is called once all dependencies are correctly wired
together and injected.

Greets, and thanks for testing,
Sebastian
