Previously, dismissing one course update would disable all future updates. But that feels a bit limiting. Instead, these are the new rules: - If the newest update has not been dismissed yet, it gets displayed. - If the newest update has been dismissed, we display nothing. - Editing the newest update will cause it to be displayed again. - New updates get displayed, even if previous updates were dismissed. This commit includes a light refactoring and addition of some utility methods to help manage the above. It also notes that the learning MFE does not use the "latest_update" waffle option, which controls the labeling of the update message.
