[TYPO3-templavoila] nested_fields contains the wrong fields

[Frederik Reiß]

Hi,

in TemplaVoila 1.5.0 (and before) the Algoritm which generates the
„nested_fields“ var is flawed. It generates

<field_before>,current_field

Instead of at least

<field_above>,current_field

or 

<toplevel_field_above>,current_field 

I wrote a patch which generates the correct nested_fields from current_field
up to the toplevel_field. But since it's my first patch for
Typo3/TemplaVoila, i'm sure it's not perfect, but at least it's more useful
than the current implementation ;)
