BGE EPY Docs: PhysicsConstraints and fixes in other modules

Browse Source 
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.

The VideoTexture module allows you to manipulate textures during the game.
Several sources for texture are possible: video files, image files,
video capture, memory buffer, camera render or a mix of that.
The video and image files can be loaded from the internet using an URL

before sending them to the GPU, allowing video effect: blue screen,
color band, gray, normal map.

The principle is simple: first you identify a texture on an existing object using
the L{materialID} function, then you create a new texture with dynamic content
and swap the two textures in the GPU.
The GE is not aware of the substitution and continues to display the object as always,
except that you are now in control of the texture. When the texture object is deleted,
the new texture is deleted and the old texture restored.
