Distinguish between settings and explicit override for external content

Summary:
This will allow KMail to properly communicate the difference also when
using per-folder settings for loading external references. This in turn
makes 746e02af07f7dc223940ad80a0a234c0aff85850 also work in that case.

Taken from KDE patches and adapted to TDE.
