Workaround the section problem

It seems that Qt have a bug with section set to FirstCharacter
to render as if it was set to FullString for newer delegates.
A workaround has been to provide the section as being only the
first letter of the field being used.
Tried to improve image handling

This uses private QImage access from QQmlImage.
Saves the images when downloaded, and use cached
files when loaded.
