HTML Widgets; More support for Apex Charts added

The following helper methods have been added to widget.UI.Charts.ApexCharts to support the creating of additional chart types:

• BarChart
• ColumnChart
• CreateXYSeries
• DonutChart
• LineChart
• PieChart

NOTE: These methods provide a very thin wrapper to create Apex Charts. For full information on Apex Charts, see https://apexcharts.com/

The "User Dashboard 1" Widget has been updated to use Apex Charts rather than Google Charts and provides examples of how to use some of these new methods.
