Update readme for Blender 2.72.
Several tweaks for Quick Smoke:

* Improved Cycles fire, patch by Gottfried Hofmann. Differential revision: https://developer.blender.org/D777

* Added Smoke + Fire type to the operator too.

* Cleanup.
Cycles / OSL: Add a conductive fresnel shader template.

This adds a fresnel conductive OSL preset to the Text Editor. Based on a patch by Lukas Stockner.
Differential revision: https://developer.blender.org/D145

See the differential for details.
Comment out SVM fresnel_conductor() function for now, still unused.
Fix building as Python module (manpage-generation)
Fix T41746: WPaint: gradient+mirror fails
Attempt to fix compilation error on ubuntu linux
Fix T41703: Blender crashes trying to load character file.

Core of the issue is that pointcache handling in depsgraph were (re-) tagging
for update some objects on hidden layers, when all their dependencies remained
untag.

Since we do not want to update objects on hidden layers, take this data into account
when flushing pointcache.

Investigations and org patch by self, reviews, advices and final patch by sergey, many thanks! :)
Fix T41573: Compositing reroute converts floats to red color

Thanks to Lukas for advices and review.
