Add support for 'Table Cell Redlines' in SW core

This patch adds support for 'Table Cell Redlines' (such as 'table cell inserted'
or 'table cell deleted' in SW core).
It adds the 'SwTableCellRedline' object, and adds a function for adding
objects of that type to the 'SwExtraRedlineTbl', which is the object
that holds all the redlines which are not 'Ranged' redlines.
