GreenHopper: Should be smarter about formatting story cards.

GreenHopper can display items in Story Card form. However, these cards don't make good use of screen space. For example, if the Description field is longer than 3 lines of text, the tool will (annoyingly) truncate the text, even though the remaining space the card uses on the screen is largely blank space!

GH should use all available space on the story card before truncating any displayed information.
