godot/scene/3d/particles.cpp
Rémi Verschelde 5fe01d4cfc Move ParticlesMaterial code to its own resource file 
It's shared by both 2D and 3D particles (+ CPU ones), so it makes sense
to have as a common resource. It also allowed to disable compilation of
Particles (3D) when using 'disable_3d'.

Also cleaned up includes in SpatialEditorGizmos and some other places,
as well as dropped dead code in material_editor_plugin.cpp.
