[TYPO3-doc] Updates TYPO3 Tutorial for Editors

[Mark Howells-Mead]

Hi guys

I've started adding new screenshots and improved text to the following
wiki pages. I'd appreciate it if a native German speaker can take a
look at the German version and correct any grammatical errors.

I've only changed as far as “3.2.1 Interaktion mit Elementen im
Seitenbaum” so far. The screenshots are from TYPO3 6.2.
