ISSummaryTable (as used in Summary Page 2s); new "HasData" property added to ISSummaryTable

A new "HasData" property has been added to ISSummaryTable, which is used in Summary Page 2 scripts.

This allows you to easily check whether a Summary Table has any data and therefore whether to add it to the collection of tables returned.

For example, the following simplistic code

If SummaryTableKey.Rows.Count <> 0 Then SummaryTables.Add("Key", SummaryTableKey)

can be replaced by:

If SummaryTableKey.HasData Then SummaryTables.Add("Key", SummaryTableKey)

The issue with the old method was that Before, After and Right Text should also be checked for values.
