[TYPO3-mvc] walk flexform recursive

[Felix Oertel]

hey guys,

i just experienced a problem with flexforms today and found this bug 
ticket [1] which discribes the problem pretty good.

at the moment extbase can not handle repeating sections in flexforms. i 
wrote a patch which makes extbase run through the entire flexform 
recursively. for me this works with normal values as well as with 
repeating sections ...

see the flexform [2] for a good example to use this.

the "el"-layer will be left out because it just indicates the elements 
and we don't need this in an array for logical reasons. the 
_arrayContainer will be skipped for the same reason.

just use the patch with the attached flexform and debug $this->settings 
in your Controller ... you will see

i don't use fancy flexform stuff this often so i really need your help 
to have a look at the code and test this stuff thoroughly. this was 
written in an hour or one and a half so chance is that there are some 
logical mistakes in it ;-)

please be so kind and give some feedback so we can get this thing to 
work ...

regards, foertel
