[TYPO3-project-4-3] flexform issues

[Steffen Kamper]

Hi,

there are several flexform issues need to be fixed.
I don't have all BT entries by the hand, so just from remember:

* translation: original is shown as complete block with sections
* array for missing input is shown at front of complete flexform
* nested flexforms cause error in t3lib_div and content isn't saved
* IRRE in flexform cause several errors

I'm sure there are some more. So it would be nice to make a 
flexform-fix-session during t3dev09
