Merge pull request #7 from zVPS/master

Fixes typo in named sed and chkconfig override for centos 7 only

I'll have to move back the fi because Ubuntu does not know nor need chkconfig : the install of the service put them on autostart too.
chkconfig is only for CentOs

Ubuntu does not know chkconfig and do not needs it because it already
setup services as autostart.
roll back: Use also panel domain to postfix
Typo in local IP detection + info easier to read
Display Tag version
Added installer/core/preconf versions in log file

of apache or mysql already installed.
Update Centos detection and few comments
Accept both adr and addr to extract local IP
