Change OK button on Advanced Preferences to Save button

[Ageless]

When using the Simple View preferences, you go out by either clicking the Save or Cancel button. When using the Advanced View preferences, you go out by clicking either the OK or Cancel button.

People now just look into the Advanced Preferences and without knowing it make them work as they click OK to go out, then later they complain on forums that their preferences on the web site don't work when they change them and update BOINC. We increasingly find that these people are unknowingly using the override preferences, because they looked in once and went out by clicking OK.

So my idea is to standardize the buttons in Simple View and Advanced View, make them both Save and Cancel. Turning them around, so Cancel is first, would perhaps also make a difference. An extra pop-up window in which you have to confirm that you want to use the override preferences, may also do the trick.
