Integrate controller

[CorradoMotta]

Issue:

A game controller should be added to move the correspondent QML sliders and control the vehicle

[CorradoMotta]

Job done so far:

• Added the following library to QT: https://github.com/alex-spataru/QJoysticks
• To solve "SDL2.dll not found -lSDL2" error, download SWDL2 mingw x64 library from: https://www.libsdl.org/download-2.0.php
• Include the library in .pro of the project.
• Created a new main.qml to show the functionality of the library and control the Thrustmaster.

Next steps:

• Learn how the library works in general
• Figure out why z-axis is not working
• Figure out how to filter input data
• Figure out how to add this to my main.qml

Basic integration is working. Need to work on issue #8 to make sure that the interface will stay stable.,

To Fix: connect button is not working if the controller is moved before!

All done.
