autoDelete has no effect when a file is replaced on model update

[rimas-kudelis]

When I replace a file with a new one (using ActiveRecord::update), the original file remains in untouched. Assuming that we always have just one link to a file (which looks like a safe assumption when autoDelete = true, I think the original file should be deleted in such cases to avoid garbage buildup.

Ah, so you have this setting already (deleteOldFile), but it's not documented! :)
