use ED_operator_screenactive rather then ED_operator_screenactive so transform works in background mode.

2 minor glitches
- removing bone groups didnt set the next one active.
- removing poselib was using int for enum rna property.

additional bake modes
(refined patch #23430)

+ specular color
+ specular intensity
+ mirror color
+ mirror intensity
+ alpha (tranparency)
+ emission (glow)

- check paths are not empty strings before making blend file paths absolute or relative.
- when saving blend file with 'Remap Relative' enabled, don't try make paths absolute if the internal filename is invalid.
- use case insensitive path comparison on windows when checking if path remapping is needed & for comparing next/prev dirs in the file selector.

cleanup only
- rename 'name', 'dir' --> 'filepath' where these actually represent a file path to avoid confusion.
- bugfix for possible (but unlikely) uninitialized string.
- remove commented script append function, now we have a python api for this.

fix [#27405] Append objects with linked materials they dissapears after save
when linking in files to an unsaved blend file, make all library paths absolute.

This fixes:
[#27422] Strobe setting does not work with effect strip
[#27421] Some Settings of Adjustment Layers are not Functional.

Render API: code cleanup.

fix for r36723 - putting extern Material inside code like that results in wrong linking. Move to proper place so that linking goes right.

Render API: RenderEngine.update_progress function to set progress percentage.

Render API: add self.report() function for RenderEngine, for reporting warnings and errors.

Render API: first step in updating RenderEngine to work according to:
http://wiki.blender.org/index.php/Dev:2.5/Source/Render/RenderEngineAPI

Cycles: panel header drawing tweak.

added other addon category.

svn merge -r36672:36725 https://svn.blender.org/svnroot/bf-blender/trunk/blender

fix for warning

fix [#27414] no-material renders differently in View3D vs BGE
when a texface layer exists this still overrides the default material.

=bmesh= fixed curve editmode crash

RNA glitch: particle path step values had soft & hard limits the wrong way around.
