[#18936] Particle Related Patch

from Alberto Santos (dnakhain)

This also adds the option to duplicate a particle system with an object.

 --- description from the patch submission.

This patch includes my latest additions to the Python API developed for my Degree's Project.

It includes:
 - Particle
    - Vertex group dictionary in doc (to use with setvertexgroup/getvertexgroup)
    - Particle.New return psys (not specified in doc)
    - Draw As variable and dict
    - Strand render toggle
 - Object
   - psys variable in duplicate
 - Material
   - Strand render variables
 - Texture
   - Use colorbands
 - Lamp
   - Spot buffer type selection
