Type system: Add attribute indicating C++ 11 enum classes

Introduce enumeration for the type to EnumTypeEntry which can be specified
by the boolean "class" attribute. For the enum classes, the value names
need to be qualified by the enum name to match the C++ API.

For the C++ generator, add an overload to
Shiboken::createScopedEnumItem() that takes a PyTypeObject and add the enum
items to the enum so that the name is in the enum scope.

     Notice that the **enum-type** tag can either have **name** or **identified-by-value**
     but not both.
 
+    The *optional* boolean attribute **class** specifies whether the underlying
+    enumeration is a C++ 11 enumeration class. In that case, the enumeration values
+    need to be qualified by the enumeration name to match the C++ Syntax.

     The **revision** attribute can be used to specify a revision for each type, easing the
     production of ABI compatible bindings.
