Harley Acheson 9a3f80b8f2 UI: Generalized Alert and Popup Block Error Indication
This PR adds an optional block alert level, defaulting to none. Then
for error-level alerts only it adds a red line and a color icon.
Dialogs with other alert types do not change at all. This also adds
a UI_alert function to create such dialogs.
