HTML Widgets; Grid; New "noLineBreak" column creation option

A new "noLineBreak" option can be specified when creating a widget.UI.Grid column.

This will prevent text line breaking in the column and means that you can specify a smaller column width, e.g., "4em" and know that the content, even if wider that this, will now cause the cell to flow over multiple lines.

NOTE: Number and Date columns should not overflow onto multiple lines regardless of this option.
