Qt Quick Designer does not support Qt Quick (Labs) Controls 2 out of the box

Qt Creator ships a "fallback qml2puppet" which is used by default. That Puppet supports Qt Quick Controils 1 by accident because the Qt libraries for Qt Creator contain that Module.

But Qt Quick Controls 2 is not part of the installation. Therefore, using the new Qt Quick (Labs) Controls 2 application wizard leads to an unfunctional Qt Quick Designer. The only way for the user is to know that there is a quite hard to find setting about an "Emulation Layer" which can fix that.

I see two ooptions to fix that issue:

• short term: Ship Qt Quick (Labs) Controls 2 with Qt Creator
• mid term: Fix whatever is broken with emulation layer build process and make that a default setting.
