Change QML Widgets to QML (before GUI)

[BoskiJanusz]

This task contains change Widgets but also it does need signal mechanisms in classes and QT macros to work properly. We should make few smaller tasks including:

• Widgets to QML
• cmake for QML
• extend classes for QML (inherit from QML and get Macros to work properly)
• extend mechanizm for C++ in QML
• signals for classes (setters shoult have comparison to limit processing)
• tests for signals (we can use QSignalSpy)
