Improve GLTF loading and Inspector (#51)
* Improve GLTF loading - If directory dragged onto window, search for `.gltf` in it. - Improve progres bar: use full-width window at bottom instead of a modal popup. - Add and use `struct Bool` as conversion-resistant alias for `bool`. * Polish up loading bar - Add title bar. - Adjust dimensions. - Make non-movable and non-resizable.
