Add a notice about the "upload" dialog

Users keep getting confused about the webkit directory selection dialog that has unfortunate wording about "uploading" that I can't change. Hopefully this new dialog that displays before the dialog I can't control will help users understand that nothing is getting uploaded anywhere.

The message can be ignored in the future with a checkbox that sets a cookie.
