Styled chart according to new and improved UX design
Merge branch 'sprint10' of https://github.com/SmartBear/loadui into sprint10
Scrollable Line Chart has been modified with some new details in styling, what remains is to make sure that elapsed time scales to the charts xAxis
Added basic styling to ChartGroupView. Rewrote chartGroupView.fxml to depend on its corresponding stylesheet and use Anchorpanes to combine Component buttons and statistic buttons in a single pane below the main chart according to suggested design. Also changed global font family to lucinda sans on UX designers request.
