* 'timeline-refactor' of https://github.com/TBITracker/taskplanner:
  Shep's a wizard (wizard label changes)
  Removed the baloney sandwich.
  Actually, changeLabel was doing a whole lot of silly work. Let's just move that all into the buildTimeline code so we only have to do it once. And let's improve the math while we're at it.
  Minor changes, a fix that will prevent the label from leaving the screen.
