made it easier?

there is no longer a requirement to be in your main network if you are
both connected to the same network it will still mount your backup
disk. Since the IP is now dynamically taken from the arp table.
Added more instructions and made it more energy efficient.
fixed some bugs like the speed of arp and arp telling it that a
host/server was not connected. all fixed. (not that anyone has used
this yet).

please if you use this make sure you fill in everything correctly. it
does not break anything but it can cause a lot of annoying things.
