New Table Element parameter - right_click_selects. Default is False. If True, then will select a row using the right mouse button, but only if
zero or one rows are selected. If multiple rows are already selected, then the right click will not change the selection. This feature enables
a right-click-menu to be combined with table selection for features such as "delete row" using a right click menu.
Fixed bug in Column element - was incorrectly checking background color for None or COLOR_SYSTEM_DEFAULT
4.55.1.8
Changed docstring for Table.get_last_clicked_postition to indicate what's returned now. Was not useful for tkinter port until recently when cell clicks added.
Better auto-sizing of Columns for Tables.
Better sizing of the row number column using the font for the header in the calculation
Use the column heading font to help determine if the header will be what determines the width instead of the data in the column
