This is a port of the Chrome extension by karthidec.
Helps to display last 4 digits of story number in story name field (collapse view). This provides a display mask to user browser screen -- this is only a cosmetic client-side change, and does not update/change the actual story name field.
By default, Pivotal Tracker does not display story number in story name field in collapsed mode.
This "short code" makes it much easier for everyone in a planning meeting to know the exact story you are talking about without having to read the name for each story to find the targeted story.
