Update from Original Minimserver to Minimserver 2

[simoncn]

Upgrading should be very simple and the upgraded version should work just as it did before as long as you follow the upgrade steps carefully and in the right order.

The upgrade steps for Synology have changed recently because MinimServer 2 is now available in the Synology Package Center. I will make new instructions for the upgrade available on the MinimServer website tomorrow and I will post here when I have done this.
