Hide dot files

["Dimitrie O. Paun" <dpaun@rogers.com>]

Alexandre, modified as follows:
  -- ., and .. are not marked as FA_HIDDEN
  -- you can turn off this behaviour by setting ShowDotFiles=1
     in the configuration file.
  -- documentation patched accordingly

ChangeLog
  Mark files starting with a dot as FA_HIDDEN.
  Add configuration option 'ShowDotFiles' to turn this feature off.
