    tools: add mirrorsfile parameter to mt torrent script, convert trackers variables to array
    
    The parameter -m specifies the mirror file path and file name instead of assuming it is in the current
    directory. The torrent trackers are now an extensible string array (in sh-compatible syntax) instead of a
    limited list of variables.
