fix bug: class Notice shows incorrect message if there's a price bump after the takedown date.
instead of showing: Supporter preregistration closes at 11:59pm PST on Friday, Dec 26
it was showing:  Price goes up to $95 at 11:59pm PST on Wednesday, Dec 31
change timezone back
put back newline (no changes)
