Implement duplicate checking for pics in FSWidget

Assume that the pictures are identical when the MD5-Sum is. Don't do
that if only the filename is identical. There can be pics with identical
names in the database. Instead, record the md5sum in a custom role.

The idea is to let the user sort it out by comparing all pictures
visually, but that's not yet implemented.
