*Some code improvements like if -> elif

- remove unused imports
- remove/comment unused vars
- fix for some bugs with unused vars being used

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
 


[[Split portion of a mixed commit.]]

rev: 32411

- added rounded rectangle to miscCurve (with some minor enhancements)
- some spell checking and cleanup

scripts tested as working

- forgot to remove debug print

- added SplatCurve

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

- fix for api changes

- 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

- as a result much more readable now

Fixed some descriptions and locations

- 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 

- testing the new button "report a bug", 
  see commit from dingto here http://lists.blender.org/pipermail/bf-blender-cvs/2010-May/028285.html
