[filebrowser] More reliable file saving in Photo Editor

[filebrowser] More reliable file saving in Photo Editor
Photo Editor used to save JPEG files with no metadata as PNG.
This is now fixed. Also added simple metadata parsers for PNG/BMP/GIF
to make thumbnail display logic in the File Manager work better.

Looks like some of the browser tests are not happy around selecting files, could
this be related?

I did not expect that, but it very well might be related. Shall I revert it?
