[BUGFIX] Incorrect placement of child elements on paste and localize into flux column

Changed so TYPO3 handles IRRE records in tx_flux_children. Only set tx_flux_parent and tx_flux_column on the copied element in tceMain->cmdmap. Changed tx_flux_parent to a readOnly input so the field is writable according to TCA. Updated/Removed tests to reflect changes.
[BUGFIX] Missing child content elements in localized parents.

When config.sys_language_overlay = 1, content elements with [Default] (not translated) and [All] languages are also rendered in the "localized parent". When config.sys_language_overlay = hideNonTranslated, content elements with [All] languages are also rendered in the "localized parent".
