// Algorithm:
// . Get the list of filters to be updated
// . For each filter run the download and checksum check operation
// . Store downloaded data in a temporary file inside data/filters directory
// . For each filter:
// . If filter data hasn't changed, just set new update time on file
// . If filter data has changed:
// . rename the temporary file (<temp> -> 1.txt)
// Note that this method works only on UNIX.
// On Windows we don't pass files to filtering - we pass the whole data.
// . Pass new filters to filtering object - it analyzes new data while the old filters are still active
// . filtering activates new filters
