Two new menu items are added:

[MenuItem("Edit/Paste Mesh from External %#v")]
[MenuItem("Edit/Copy Mesh To External %#c")]

Deleting pasted meshes will leak in editor (but adding a
DestroyImmediate will break Undo...). A fix probably means creating
meshes as project assets instead of scene instances.
At the moment meshes are assumed to be in left handed coordinates.
Export has a way to change this, but import does not.
Multiple meshes aren't exported, only the first selected. In the future
it would be nice to merge multiple meshes.
Materials, bone weights, UVs, and morph targets aren't imported.
Import always triangulates meshes. Unity does support Quads, so it would
be nice to keep that topology where possible.
