Upon registration close out, auto-update app's text to specify that registration is now closed

[emelcher1]

The app's admin can set a timeout for when registration is to close. When this timeout occurs and registration is closed, in addition to hiding the registration login button, also auto-update the text on the site to specify that registration is "now closed."

Specifically, modify the text of "Registration is now open for the second annual Campus Codefest!" to something like: "Registration is now closed for the second annual Campus Codefest. Please join us next year!"
