Added default puppet.conf file.
Added Apple services (HFS+, AppleTalk, Time Machine).
Updated server setup script.

The script now sets the hostname in three ways: through the `hostname` command and by setting both /etc/hostname and /etc/hosts. You can also pass a server name along with the script (as $1) to set your hostname. If no name is passed, the variable inside the script ("server name" by default) is used.
