Readd Scrape Function to Cli

[Danez]

the option -s was deleted between 0.7 and 0.8.

We from torrentflux-b4rt would like to see that feature again as we use it to display a chart of this data.

I don't know if it is possibly atm in general and if there are functions in the core for this task.

thats amazing! thanks a lot.

But I think the scrape-block needs to look like this, i tested it and it works:

 if( showScrape )
     {   
        printf( "Scraping, Please wait...\n" );
        const tr_stat * stats;
        
        uint64_t start = tr_date();
        
        do
         {
            stats = tr_torrentStat( tor );
            if( stats == NULL || tr_date() - start > 20000 )
            {
                printf( "Scrape failed.\n" );
                goto cleanup;
            }
            tr_wait( 2 );
         }
         while( stats->completedFromTracker == -1 || stats->leechers == -1 || stats->seeders == -1 );
        
        printf( "%d seeder(s), %d leecher(s), %d download(s).\n",
            stats->seeders, stats->leechers, stats->completedFromTracker );

         goto cleanup;
     }

Corrected patch (as per Danez head up on it ;-)). Also tweak the output, so that it shows % done and % found while checking a file.
