Set reasonable background color for docs toolbar...
Set reasonable background color for docs toolbar Default background color was white, which caused white on white text in linux assistant, which is for some reason unable to render the background picture for the toolbar. The real bug is probably in assistant, but at least with this workaround docs are usable. Task-number: QTRD-1480

Updated mapper classes descriptions
 r1397 Model mappers allow you to use QAbstractItemModel derived models as a data source for a chart series.
Marek Rosa
Model mappers docs updated
 r1378 Horizontal model mapper is used to create a connection between QXYSeries and QAbstractItemModel derived model object.
It is possible to use both QAbstractItemModel and QXYSeries model API. QXYModelMapper makes sure that QXYSeries and the model are kept in sync.

Replaced NOTE: with Note: in modelmapper classes and qdatetimeaxis to remove it from QtCreator TODO entries
 r2396 Note: used model has to support adding/removing rows/columns and modifying the data of the cells.
