Subject: [PATCH] implement logging system on dashboard.

The code added here is more about populating the area created for logging each web request. The XAML code was done in the previous commit. As I stated there, these logs are more about the providing the user of this program visual feedback about the state of the program. There are times when the various devices (light meters/relays) don't update and it's hard to tell if that's Eyes and Ears, the internet connection or the devices on the other end.
