Properly read the mesh from LUA.

Players can now be set to meshes using the following test script:

function switch_player_visual()
		prop = {
			mesh="player.obj",
			texture="player.png",
			visual="mesh",
		}
	for _, obj in pairs(minetest.get_connected_players()) do
		obj:set_properties(prop)
	end
	minetest.after(1.0, switch_player_visual)
end
minetest.after(1.0, switch_player_visual)
