Updating copy for final few days
Introducing new template for countdown timer. Hopefully it's fairly self explanatory as to how this view should work! The ending time of the KS campaign is 6pm (Vienna time) on Monday.
* Separated the two stretch goal wordings into two files and subsequently extracted stretch goal logic into own handler
* Used different maxAge and checkInterval settings for different file types
* Fixed "" strings to '' strings
* Added countdown support
Generic wording (not for ghost branch)
