There was a case where the device status would change to the 'low light detected' (light sky blue) when on the border between a weld being detected and not. This commit addresses that. Also, both Light Meters have been installed at this point and it is apparent both of the welding booths have different light levels. Becuase of this, the dashboard now has code in place which seperates the update-checks to match the device/welding booth. In other words, factory1 does not go dark see green at factory2's light levels.
The logic for 'factory3' and 'gallery3' is still in place but is not bound to the view (MainPage.xml). The view xml is commented out and not removed. This should make it easier to re-add it if the need comes about.
'factory2' was not updating its timestamp when it received a new reading. It was binding to the wrong property in MainPage.xml (view model). This changes the property to the correct one.
