[FEATURE] Improved recursive setting inheritance

The recursive level of the starting point can be reset to zero in the
FlexForm settings but can also set to an empty string so that the
setting is inherited from the TypoScript settings.

For this to work the overrideFlexformSettingsIfEmpty behavior is
modified, so that it only will treat empty strings as empty values but
zero integers will be treated as set values.
