Added explanations of the consequences of choosing highlighting or
shading for export to MS Office. Each choice has an advantage and
a disadvantage, and these are inverse to each other, so seemed better
to give clear information so that users can make an informed choice
that is relevant to their situation, rather than try to recommend a
better or preferred choice.
Also:
+ added information about default setting in different LO versions
because some users might have files exported with older LO versions.
+ added <tip> about using compatibility filter in "Character
Highlighting Color" dialog box.
Thanks to Justin Luth and Mike Kaganski for expert advice.
