Many source file name and data type are prefixed by "skeleton" before, now all are refactored.
The class MeshResultContext represents the outcome of mesh generation before, now we have material, pose and animation, so we just rename it as Outcome.
Besides adding the PBR material manager, this commit hide some unnecessary features such as toggle wireframes and toggle normal smooth.
Add a regenerate button to indicate mesh is generating by showing a spiner, user can click this button to regenerate if the final result is not good.
Please note that, we generate the texture map by default compared to before we only generate texture map when user export glTF result. Current uvunwrap library cann't handle bad mesh very well, so it will crash on the wires model.
Before, app crash on some machines as been reported in #15 and #16, and cannot easily be reproduced on other machines, such as a virtual box guest system, which make it very hard to trace the root cause.
Now, the offline render is totally removed from the code base, instead of offline-render to image then show the image, we can directly show the parts model in the parts tree using normal opengl widget, and the result looks better than before.
