put hours back in _recently closed_ list

[arkadianriver]

They were converted for Gantt chart and they're still that way. Put back to normal.
Or better, convert to story points with a configuration option of what you consider to be a story point. (ie. "storyPointsPerDay": 2)

Might eventually opt to going back to recording story points instead of hours with "hoursPerStoryPoint": 12 instead.
