[SoC] Report: Worker threads in sextante batch and history modes

[Camilo Polymeris]

Hello all,
you can read this week's report for QGIS/Sextante here:

http://sextante-gsoc.blogspot.com/2012/06/worker-threads-now-in-batch-and-history.html

Now that the code is a bit more mature, I am committing changes
directly to the sextante svn.

Regards,
Camilo
