Update to 2.8. Changes:

o The code is now modularised. The distribution contains 'Mirmon.pm',
  an OO interface for mirmon objects. Program 'mirmon' still contains
  all the code ; it is split into 'Mirmon.pm' and 'mirmon.pl'.

o The mirror list can now have rsync urls.
o The algorithm to balance the probe load over the hourly mirmon runs
  is improved ; from completely skewed to balanced takes some 5 days.
