#30 AMaViS-ng quarantine disable

[Randy Smith]

I see that the code supports disabling quarantine if
$cfg_quarantine_dir is not defined however, there is no
way to undefine it from the config file because it gets set
to the default value. I created a small patch to work
around this issue by creating an option in the config file
named 'do quarantine' that turns on or off the quarantine.
(Defaults to on.) 'do quarantine' takes one of two values,
'yes' or 'no'.
