Create proper .qmltypes files

[raven-worx]

Since the qml-plugins are compiled for android they can only be loaded by qmlplugindump tool also compiled for android. It needs to be checked if the lack of Q_OS_ANDROID macro has any impacts on the interfaces of the exported QML types. If no the .qmltypes files need to be created out of a build for a desktop platforms.

(maybe add build-steps to call qmlplugindump tool for non-android target builds)

see http://doc.qt.io/qtcreator/creator-qml-modules-with-plugins.html#generating-qmltypes-files
