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

- Bug fix: hasSmokeSimulation lacked parenthesis

- Summary page now lists border render
- ore.prepare now changes border render off
- ore.prepare now changes full sample off, then save buffers (old was just save buffers which can't be changed if full sample is on)
- A small piece of text that warns about the upload making Blender seem frozen
- Bug fix: ore.prepare() couldn't be called in the old way. The new API prevents changing data during layout drawing. The original ore.prepare operator was changed a bit to not require the call
- Bug fix: Completed / pending / rendering sessions didn't work. Same issue as above: cannot change data during draw functions. Fix is simply removing the problematic call as the list is already generated elsewhere

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.]]

- Test render button
- Simulations to the summary page

Fixed:
- Bug that forced the user to press Check Scene again even if all was in order

Added automatic external data packing to avoid problems where the user submits a session without textures

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

* add tests for nodes.
* update poll() usage to be according changes in blender

- 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

- moved renderfarm to render_renderfarmfi.py
- fixed bl_addon_info: new wiki page, tracker page, category
