[Typo3-doc] FE Diagram

[Patrick Gaumond]

I've created a new page on the Wiki to try to get together some 
diagrams... I've put the one from Inside TYPO3 and the one of Peter.

I've also did a "text" version from my understanding on how FE works, 
hoping to get some people look at it and then create a great graphical 
one that could be useful for any developer.

Please, be my guests at:
