New app: reverted to the hard-coded run/history SKBTestOverviewCell layout, as there are issues with the storyboard approach which we don't have time to deal with at the moment.
New app: SKBTestOverviewCell - in general, align text left rather than centre, as this looks much neater.
New app: Better layout of activity indicators / spinners - position these left-x, center-y (before, they were center-x, center-y), which looks much nicer in SKBTestOverviewCell
New app: Summary / Run/History screens and SKBTestOverviewCell:  use bold text for "Download, Upload, Latency, Mbps, Date" to allow them to be seen more clearly.
New app: Allow the app to not display information on best target.
