TestAttachDriver doesn't reset properly #1975
Description
Like many of the physics apps in jme3-examples, TestAttachDriver includes a "Reset" function. When the return key is pressed, the test is supposed to go back to its initial state.
However, the "Reset" function doesn't reset the linear and angular velocities of the bridge. If the bridge was in motion when the return key was pressed, it resumes that motion after the reset.
