[TYPO3-mvc] own Tx_Extbase_MVC_Exception_InvalidArgumentValue handler

[Simon Schaufelberger (Schaufi)]

Hi,
thank you for your response!

this is actually not what i expected as an answer since i have to do 
everything completely different and i don't really want to do extbase 
validation by hand if extbase does that for me.

Regards, Schaufi
