Make QColor understand #AARRGGBB

This way I can have in my QtQuick something like
Text {
 text: "<font color='#ff0000'>H</font> <font color='#99ff0000'>H</font>"
}
and it works properly

QtQuick already supports #AARRGGBB for color: properties so I've
decided to go the notation

Once this is merged we can remove the extra code
in QQuickColorProvider::QColorFromString

I've also added some tests for the hex -> QColor conversion that where
non existent
