tdf#38194 tdf#106556 Enhancement to highlight direct formatting,

paragraph style, and character style use in Writer documents

Initial commit to realize direct formatting, paragraph style, and
character style highlighting enhancement requests.

Highlighting of character direct formatting is turned on/off using
.uno:HighlightCharDF. Highlighting of paragraph styles and character
styles is turned on/off using a check box in the Sidebar Styles panel.
Closing the Sidebar also turns paragraph and character style
highlighting off. Paragraph direct formatting is indicated by a hatch
pattern over the paragraph style highlight bar and also by "+ Paragraph
Direct Formatting" appended to the tooltip that appears showing the
name of the paragraph style when the mouse pointer is over the style
highlight bar.

Colors used for styles highlighting are determined by a hash of the
style name. Lightgray is used for character direct formatting.

Known issue:

Tooltip doesn't show for paragraph style highlighting in tables and in
frames where the highlighting bar is drawn outside of the frame.
