/**
 * @ingroup gtk
 * @file
 *
 * Keep track of which files we send away, and how often.
 *
 * Statistics are kept by _FILENAME_ and file size, not by actual path,
 * so two files with the same name and size will be counted in the same
 * bin. I dont see this as a limitation because the user wouldn't be able
 * to differentiate the files anyway.
 *
 * This could be extended to keep the entire path to each file and
 * optionally show the entire path, but..
 *
 * The 'upload_history' file has the following format:
 *
 *		- "<url-escaped filename> <file size> <attempts> <completions>"
 *
 * @todo
 * TODO: Add a check to make sure that all of the files still exist(?)
 *       grey them out if they dont, optionally remove them from the stats
 *       list (when 'Clear Non-existant Files' is clicked).
