- fix error when a mesh had a None material
- no need to set the object as avtive when assigning materials

Dear all.

Here comes version 1.2 !

New 
===
1. Double and tripple bonds can now be displayed. The option 'bonds' needs to be
checked. One can also choose the distance between the sticks.

2. If the bool 'smooth' is checked the shape of the sticks is more round.  

Changes
=======
- Buttons, which depend on other buttons, are grayed out as soon as the
'master button' is deactivated.
- Other small bug fixes


With this version 1.2 I consider the PDB project as 'accomplished' so far. 
Of course, I will keep an eye on any critics, changes, bug fixes and so on. 
Please, let me know if you find any bugs. Thanks.



Happy New Year!

Dear all.

1. New option: sticks connecting atoms can have now the color of the atoms.
2. New button in the panel: 'Show sticks' scales the atom radii such that only
   the sticks are visible.  
3. A bug was removed: Scaling atoms with a specific name scaled also the sticks.
   This does not happen anymore.  

- Due to the changes, the script has version 1.1
- To be done: Update of both Wiki pages (next days)
- Probably, I commit a 2nd time today.

correcting smoke domain modifier type restriction

Patch by Philippe Van Hecke

- fix handling of pointcache dependencies on slave (correct repathing) and on client (bad frame dependency range)
- add Force Upload option on master to force dependencies upload and download (don't reuse local copies outside of slave cache)
- add links back to main page on job web page
- client limit dependencies to rendered frame range (it used to add all point cache frames)

Thanks to Philippe Van Hecke for raising the issue by email.

Dear all.

1. Changes of the 'Atomic Blender - PDB importer' panel. I've 
grouped specific in/outputs and buttons by using boxes. Now,
there is some order in the panel.
2. Better precision for sticks
3. No other changes otherwise ...

[[Split portion of a mixed commit.]]

add missing route command for H3D export, I wasnt able to get this working but I think it _should_ work, needs further investigation.
