The preferences dialog should indicate which settings are overridden by project settings

[elextr]

If a setting has a project override changing it in the preferences dialog will appear to not work, but its not visible that this is because of the project override. The user must be aware that the project overrides, but it does so for only some settings so its easy to forget which ones they are.

The preferences dialog should indicate those preferences overridden by project settings.

@shiftee thanks for the references, I was sure there was a longer discussion somewhere, but never mind.

Suggestions are welcome of how to make it visible that this setting is overridden in a way that does not intrude too much for experienced users, but is understandable to new users (without them reading the manual, and thats the hard part).
