Title: Stop user input while saving subtitles (#1330)

Extended idea of the loading modal to a "freeze box", which is a modal
dialog that has no buttons or other ways to exit. We show a freeze
box when we're saving subtitles, approving tasks, exiting, or other
times when we don't want to allow any user input.
