[Releasing] Adding Enginio (qtenginio) to the Qt release

[Frederik Gladhorn]

Hello,

we (some of us at Digia) have been working on Enginio - a convenient cloud 
storage for Qt applications. Since the library is actively maintained we would 
like to integrate it into the official Qt release for Qt 5.3.

For those curious now, there is already the option to get it when using the Qt 
5.2 online installer.

For more information see http://engin.io
