Content review servers

[paulcobbaut]

The Servers (aka advanced) book now builds, but its content should be reviewed. Some chapters (like selinux) are a mess. I will slowly start doing this for most of the minibooks here.

This requires quite some work for:
minibook_samba (must be done before October 2011)
minibook_dns (must be done before October 2011)
minibook_dhcp (must be done before October 2011)
minibook_router
minibook_firewall (must be done before December 2011)
minibook_webserver (must be done before December 2011)
minibook_ipv6
minibook_database
minibook_selinux
