Long live QColorConstants!

QColorConstant is a C++11 version of Qt::GlobalColor, except that instead
of Qt::red being an enum, QColorConstants::red is an actual QColor instance,
a bit like in the Qt 3 days.

In addition, the SVG names that QColor understands are also available,
with the same values. Technically, when building a QColor from a color
name, QColor ignores casing and whitespaces; we stick to the SVG/CSS
official color names (which are lowercase), and prefix them with Svg
to clarify where they come from. For instance, note how SVG's gray
is not Qt::gray.

[ChangeLog][QtGui][[QColor] Added QColorConstants, a namespace
containing constexpr QColor instances.

+    \brief The QColorConstants namespace contains QColor predefined constants.
+
+    These constants are usable everywhere a QColor object is expected:
+
+    \code
+    painter.setBrush(QColorConstants::Svg::lightblue);
+    \endcode
+
+    Their usage is much cheaper than e.g. passing a string to QColor's constructor,
+    as they don't require any parsing of the string, and always result in a valid
+    QColor object:
+
+    \badcode
+    object.setColor(QColor("lightblue")); // expensive
+    \endcode
+
+    \section1 Qt Colors
