Implement color role AccentColor in QStyleSheetStyle and QCssParser

The color role AccentColor has been added to QPalette.

This patch implements the new color role in QCssParser and subsequently
in QStyleSheetStyle.
The QBrush variable names used to populate brushes, have been changed
into speaking names for better code readability.

tst_QCssParser has been adapted accordingly.
The test function accentColor() has been added in tst_QStyleSheetStyle.

Documentation has been updated.
