make addons blender versions consistent

version info is now located on the wiki page for the script/s

Plus a few styling enhancements.

[[Split portion of a mixed commit.]]

* Modified the "Add X,Y,Z Function Surface" part:
* Changed how wrapping is done to avoid generating unnecessary vertices and make the result more intuitive.
* Added helper functions the results of which can be used in x(u,v), y(u,v), z(u,v).
* The script can now close the ends of an U-wrapped surface.
* It's now possible to create multiple objects with one set of formulae.

add mesh extras, gemstones, twisted torus, gears & 3d function surfaces
Now in folder add_mesh_extra_objects under 1 init file.

update_tag() tags for depsgraph update only, update() executes normal recalculation and creates edge data.

from Lawrence D'Oliveiro (ldo)
for add_mesh_pipe_joint.py only.

Also use blender module for adding objects.

only for the 3d function surface.

READ THIS TO AVOID A LOT OF WORK!

New way of linking to tracker pages: just use the parameter "aid" (artifact ID),
to avoid a lot of manual updates later in wiki and svn.

Example:
=========

OLD WAY TO LINK TO TRACKER
-----------------------------

Complete url of a script in Upload
http://projects.blender.org/tracker/index.php?func=detail&aid=25349&group_id=153&atid=467

If we move this in contrib this url will become
http://projects.blender.org/tracker/index.php?func=detail&aid=25349&group_id=153&atid=468
467 becomes 468, so we have to update this in wiki page.

Later on, when this moves into Trunk, the url will become
http://projects.blender.org/tracker/index.php?func=detail&aid=25349&group_id=153&atid=469
468 becomes 469, so we have to update the url in wiki page and svn.

Annoying!

NEW WAY TO LINK TO TRACKER
-----------------------------

Best way to link to tracker page is using:
http://projects.blender.org/tracker/index.php?func=detail&aid=25349

Use "func=detail"
Use "aid"            (which is the "artifact ID")

DON'T use "group_id" (which is the project ID, bf-extensions is project 153)
DON'T use "atid"     (which is the "artifacts tracker ID")

Like this, the url is unique, and we will avoid to update wiki pages and svn after moving pages

* Hopefully fixed bug where uMax was never reached. May cause other stuff.
* PEP8 compatibility
* Version & revision update

rev: 32411

scripts tested as working

by Filiciss Muhgue (filiciss). Thanks a lot!

Part 2: Extensions

- comforming after my commit in bf-blender:
  - removed the categories from addons names
  - made 'version' a tuple of integers
  - added 'api' field
  - formatted wiki and trackers pages and added where needed (empty pages are yet to be written by the authors though)

- more conforming:
  - 1 tab = 4 spaces

- please check everything is fine in case I made some gross mistake

- mesh_surface_sketch.py
- render_renderfarmfi.py
- space_view3d_align_tools.py
- object_cloud_gen.py

also move bl_addon_info to the top for faster parsing.

These scritps still need changes related to parent classes
- mesh_surface_sketch.py
- render_renderfarmfi.py
- space_view3d_align_tools.py
- object_cloud_gen.py

- every script is now (2,5,3)
- added warning field in bl_addon_info so every dev knows about this: when "warning" field is not empty, a warning icon appears and text alerts 
users about a buggy script (this is used during development, released scripts should must have this empty of course)
- formatted scripts info like this
  - GPL
  - docstring
  - bl_addon_info
  - imports
  so that the actual script starts after the bl_addon_info dict
- removed old 2.4x cruft like __url__, __bpydoc__, __author__ etc, not needed anymore (when the case integrated info with bl_addon_info and in 
case of one email meta just put it in the GPL)

- next commits I plan to do contrib scripts and conform io scripts naming 

Re-call function is removed.

[[Split portion of a mixed commit.]]

- added tracker_url to most of the current scripts in release, 
  see http://lists.blender.org/pipermail/bf-blender-cvs/2010-May/028285.html
- apparently missing tracker pages for 2 scripts:
		- io_anim_camera.py
		- io_mesh_stl.py
- wiki links:
	- added link to space_view3d_materials_utils.py
	- conformed link in import_scene_unreal_psk.py

- removed view alignment in the object creation
- added view alignment through align_matrix in the invoke

- if the 'VIEW' alignment preference is set and the object properties are changed
the object is rotated always to the view alignment of the view when the operator was called.
--> doesn't snap to new view rotation when orbiting around object and changing properties.

* createFaces can now "Flip" faces and create fan/star like faces.
