redUniverse: Clean-up and some New Features

clean-up #26:

My redUniverse quark still has a lot of features missing that I want to put in. It is endless work and I only get to it now and then. But at least after today the help files are in a bit better shape, and examples are changed to use animate to run more smoothly (most now look a lot better!).

• new help files for RedHiddenObject, RedParticle, RedBoid, RedRock, RedFood, RedAgent.
• slightly changed formatting for almost all the other included help files.
• wrote addForceWander1D and addForceWander3D methods for RedBoid.
• wrote addForceAngular3D, pendulumOffset3D, pendulumLoc3D.
• added 2 boids examples and 1 pendulum to show the new features.
• changed almost all the other examples to use animate instead of play and to close the window at cmd+.
