[Development] Qt Purchasing in Qt 5.6

[Eskil Abrahamsen Blomfeldt]

Hi,

Qt Purchasing is a commercial add-on module developed by The Qt Company 
which implements a cross-platform API for in-app purchases on iOS and 
Android. In order to make it easier for third parties to contribute new 
backends for the API, we want to release it in the Qt Project under 
LGPLv3/GPLv2/Commercial. I propose to include it as part of Qt 5.6.0.
