tdf#135774, tdf#114799 Char highlight: apply to numbering

This is a partial revert of LO 7.0's
commit 315d56582f8a56d8f2d3ea6cda63ea4832249608

The character background is exported as either w:highlight
or w:shd, based on a user setting. w:shd does not affect
numbering in MS Word, only the 16 color w:highlight does.
(tools - options - Load/Save - Microsoft Office -
 Character highlighting export as: Highlight or Shading)

I replaced tdf114799.docx with a version that uses w:highlight
instead of w:shd. The test was doing it backwards - MS Word
was NOT highlighting the numbering in the original unit test.

I added another test using the original unit test to ensure
that the numbering was not affected by the paragraph's
char shading.

There are many other "Char highlight:" patches in 7.2
that are not going to be backported.
See http://wiki.documentfoundation.org/Documentation/CharHighlight
for more details about this topic.
