* public/v2/app.js:
(App.DashboardPaneProxyForPicker._platformOrMetricIdChanged):
(App.ChartsController.init):
(App.buildPopup): Renamed from App.BuildPopup.
(App.InteractiveChartComponent._constructGraphIfPossible): Fixed the bug that we were calling
remove() on the wrong object (an array as opposed to elements in the array).
(App.InteractiveChartComponent._highlightedItemsChanged): Check the length of _highlights as
_highlights is always an array and evalutes to true.
