Add native Wayland support

[archerallstars]

I try to launch Dust3D with QT_QPA_PLATFORM=wayland ./dust3d-1.0.0-rc.6.AppImage. This is the return I am getting in the terminal:

$ QT_QPA_PLATFORM=wayland ./dust3d-1.0.0-rc.6.AppImage
This application failed to start because it could not find or load the Qt platform plugin "wayland" in "".

Available platform plugins are: xcb.

Reinstalling the application may fix this problem.
Aborted (core dumped)

Without native Wayland support, the app UI is very blurry.

About info:

Dust3D 1.0.0-rc.6 (version: 1.0.0.36 build: Apr 12 2020 11:22:47)
opengl: 4.6 (Core Profile) Mesa 22.1.7 shader: 4.60 core: true

I am running the app on openSUSE Tumbleweed.
