Removed (commented out) Baking from the interface until we work on it again. More important issues need to be solved first. 

- Automatic indentation in Pov file
- Added "command line switch". (Option to set some command line parameter)

-POV file formatting improvement with UI option and function to handle all tabs/spaces indentation (big clean up)
-use of quote characters made more consistent.

-pov max trace level (ray depth)
-pov radiosity importance sampling
-Higher Radiosity samples count (allows Halton sampling)
-pov pretrace_start / pretrace_end
FIXED
-incomplete tooltip for pov low_error
-sky_sphere mapping options:
-world sky gradient to follow pov coordinate system
-Skysphere rotation made independant from camera
-generation of skysphere with image map and BlendSky will just consider the texture for now.

All issues reported here 
http://projects.blender.org/tracker/?func=detail&atid=469&aid=23145&group_id=153
by Constantin Rahn, except Layer selective export, adding it to maydo list

fixed two typo errors and a compatibility for gamma syntax

-Added Distance based Depth of Field (not object based yet)

-Noticed a bug when parts of an object are flat shaded and other parts smooth shaded, not solved this yet.

I had forgotten to change some names I hope it does work  now; This is an adaptation of Povray exporter to render with povray 3.7 
if you want more info, there are pdfs in the zip files here on the tracker: https://projects.blender.org/tracker/index.php?func=detail&aid=22717&group_id=153&atid=468

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

After discussion with Campbell I've made povray an addon as a package (will remove from bf-blender).
Please roport any glitch or mistake I might have done while porting.
