This patch adds support for 'Table Row Redlines' (such as 'table row inserted'
or 'table row deleted' in SW core).
This is done by adding a new object called 'SwExtraRedlineTbl' that holds all
the redlines that are not of type 'SwRangedRedline'.
Also this patch adds a function for adding these types of redlines to the
'SwExtraRedlineTbl' object.
It also further develops the 'SwTableRowRedline' object.
