Connection Status should inform tooltips

[teddyrendahl]

If we have a disconnected channel, this should be visible in the tooltip . There are already plenty of hooks to determine the connection state. For instance if we are disconnected we can not know the interlock state, therefore the tooltip should say disconnected instead of True or False

Would you also like it to be available through the property used for the stylesheet?

Probably a good idea
