Pfsense 2.1 and HAVP - change access permissions

[ataru78]

I noticed that after installing HAVP have changed the access rights to the folder /var/log
Now:
drwxrw-r–  4 havp    havp    1024 Jul 12 05:33 log

This cause a lot of problems, especially if in the dir "log" are also present logs of other instruments (like squid)
