This patch allows the new background/highlighting tab page and derived
from area tab page to work correctly in the same tab dialog. It also
provides a cleaner way to use the new background tab page by setting
brush item as fill attributes to target set in the background tab page
created method.

Previously if the new background tab page and the area tab page were
used in the same tab page dialog one would affect the other due to the
same use of pool fill items. This patch makes a local copy of the
attribute item set passed and then passes that set along to the parent
class area tab page on each activation/deactivation.

Tab page dialogs that use both the background and area tab pages are:
Writer Paragraph Styles, Impress Presentations Styles and Drawing/
Graphics Styles, and Draw Drawing/Graphics Styles.

All new background tab page merged patches have been reworked in this
patch and remaining old background tab pages, with the exception of
Report Design, have been replaced by the new tab page.
