Add hashes to images
Upon successfull reading an image file, this computes a SHA1 hash of the
image and saves it with the picture tag in the log file. When a file is
not successfully loaded (for example because the log was created on a
different computer) we look up the hash in a dictionary that maps hashes
to local file names.
That dictionary (actually two for both directions), is loaded on startup
and saved upon destruction of the main window.
