Draft: Add a basic Home QML View

This a very basic skeleton to start porting the Home view to QML (#16).

The very next steps to fix would be:

• Add the qml files to qrc (now it is hardcoded to my local source dir)
• Use an actual sections model

From there on:

• Create a KMM qml plugin to communicate QML and C++
• Use the Home settings to arrange the different sections
• Figure out the better way to export the data (models, objects, etc)
