BGE EPY Docs: PhysicsConstraints and fixes in other modules

PhysicsConstraints module documented by Jean-François (Ninja Goliath) based on GameKit 2nd ed.
Thanks for the initiative and the great help!

General advice for anyone helping with EpyDocs:
* use :: instead of : to keep the indentation correct,
* use B{} for clarity when needed (e.g. createConstraints)

Adding F13 to F19 to complement Matt's recent commit
* There are other (not so important) functions in PhysicsConstraints module that are not exposed in the documentation right now.
