Network setup now uses dotconfig file instead of
/etc/network/interfaces. It supports now DHCP Only, DHCP Once and Static
IP.
After any change in the network configuration the WRS reboots. This
shall be changed when the proper script performs this action properly.
In functions.php, checking, adding and deleting "pairs" in dotconfig
have been developed to make it easier for the configuration of different
services.
Dotconfig backup file includes the current date of the backup file.

New and improved help messages have been added.
