Hotload for QML - Video

In this second video, Christoph presents the technique of "Hot Reload" allowing for quicker turn-around times in embedded development using Qt/QML.

For this, 3 steps are necessary:

1. Add a mechanism (Loader + FileWatcher) inside QML that triggers a reload when a sourcecodefile changes.
2. Add a File-Watcher to detect when a file is saved on PC. This then triggers a synchronization to the embedded target source code folder.
3. Modify the QML Engine to clear the Component Cache on reload to make it work.

Thanks go to silgon on stackoverflow for the quick file-sync solution: https://stackoverflow.com/a/40525217/394218
