Allow to load a urdf file in the testplugin.cpp, as first quick test, example pybullet script:

import pybullet as p
p.connect(p.GUI)
pluginUid = p.loadPlugin("E:/develop/bullet3/bin/pybullet_testplugin_vs2010_x64_debug.dll")
commandUid = 0
argument = "plane.urdf"
p.executePluginCommand(pluginUid,commandUid,argument)
p.unloadPlugin(pluginUid)
