Comment 7 for bug 45690

It occurred to me that the clearest fix for this might just be to rename the main Cancel button to Quit (and also consistently use the verb "quit" in the dialog). Then, as Matthew says, Cancel will no longer be associated with quitting the installation.

I haven't changed Cancel to Don't Quit in the quit dialog. This is partly because I think it shouldn't be necessary, and partly because as usual GTK makes it awkward to use a stock icon with some other text and I'd rather not mess around with this if I don't have to. This could be changed in the future if it still causes confusion, I suppose.
