Profile: add "synchronous" mode for picture plotting
The thumbnails were fetched in the background to achieve a
snappier UI. The problem with that is that on LaTeX etc.
export only placeholder thumbnails were shown.
Therefore, implement a synchronous mode. This only tries
to fetch cached thumbnails or calculate thumbnails for
images. Videos and remote files are not supported.
Fixes #1963
