pi-hole/automated install/uninstall.sh
ryt51V 9a68adf36f Big sudo refactor.
In general:
- Each script reruns itself as either root or pihole.  Any $SUDO variables are removed.
- Two new scripts are created that need to be run as root.
- The installer creates a file in sudoers.d that allows the pihole user to run the above two scripts as root.

piholeReloadServices.sh: Script to reload dnsmasq (or start it if required).

piholeSetPermissions.sh: Script to set the permissions on /etc/pihole

basic-install.sh:
- Copy two new scripts.
- Set owner and permissions on /etc/pihole
- Install the sudoers file to allow the pihole user to run certain scripts as root without a password.

uninstall.sh:
- Remote two new scripts.
- Remove sudoers file

gravity.sh:
- Rerun as pihole user.
- Use sudo for setting permissions and reloading services.
- Replaced chmod 777 with piholeSetPermissions.sh.

blacklist.sh, whitelist.sh: Rerun as pihole user.  Use sudo for reloading services.
chronometer.sh, piholeLogFlush.sh: Rerun as pihole user.

setupLCD.sh: Rerun as root.
