[TYPO3-mvc] Fluid: form.select view helper and empty default item

[KimPixel]

Hallo Laurent

I cant believe that this simple requirement is so hard to get work ...
But i need a solution for this.

With the extension of classes is a cleaner way to do this (instead of
the hacking the exbase files like Steffen do).

So can you give me more Information to do it your way?
I don't now to archive this with your small description.

Greetings
KimPixel
