release: update script to diff against 1.4.2
release notes: update text in groups and nicer formatting
[l10n] Swedish update
Set same resolution in JPEG header and EXIF

What we did is perfectly fine according to the standards, however some
applications like the Telekom cloud seem to be confused by that. This
hopefully fixes it.
Hopefully fix build without libsecret (openSUSE 12.2, 12.3)
Generalize c9f81bb fix to FindColor, FindDBUSGLIB and FindVTE modules.
