[TYPO3-doc] collaboration: Introduction - completing the list of existing Intoductions

[Jakub Tesinsky]

In the line with previous discussion we try to make one palce of wiki as 
good as possible and perhaps derive some general knowledge from this 
effort. The part is currently [[Introduction]] = 
http://wiki.typo3.org/index.php/Introduction

As far as I see there are alredy all known "Introductions" linked on the 
page. Please look at the list and let me know if you can come up with 
something more.
