Subject: Add support for enum declarations in QML

Enums can be declared with the following syntax:

enum MyEnum {
    Value1,
    Value2
}

Grammar changes done by Simon Hausmann.

[ChangeLog][QtQml] Enums can now be declared directly in QML.

Task-number: QTBUG-14861
Change-Id: Ic6b6e032651d01ee2ecf9d5ce5734976cb3ad7ab
