changes sidebar: Use images instead of texts for types of changes in Writer.

This is a Writer-only change because:

1) Calc does not have the changes sidebar yet.

2) The redlines in Calc have more complex descriptions (like 'Deleted
   column'), so postponing that for now until I have a good list of the
   possible values there so that I can ask for the icons.
