Fix missing cycles update when tweaking some render layer settings.

code cleanup: use axis_angle_to_quat() to simplify turntable view rotate code.

fix for editmode UV hiding with edges, was also using deprecated flag (UV_SELECT_FACE)

Cycles: add render layer use environment option to disable world lighting on
individual render layers.

Fix own typo in previous commit for dupligroup offset

Increase limit for game simulation steps to 50, made it hard limit.
Soft limit is still 5, so should be pretty safe even if it's not
supported well in all cases.

Move "From Cursor" operator which sets dupli group offset to own operator

Previously it used to use cursor location from time when panel was drawn,
which in some cases lead to using previous cursor location instead of current.

Fix #30876, #30932: crash in material preview render after undo or file load,
due to old material copies hanging around in the preview database.

This crash happened pretty randomly, but was especially noticeable when using
node groups.

Node Editor / Properties Region:
* Improved checks for Grease Pencil and Active Node panel, so the panel only gets shown when there is valid data, rather than showing the empty panel.

Thanks to Lukas Tönne for some help! :)

fix [#30936] Face Inset gives bad UV's

Fix related to #30928: missing image editor update when changing active image
texture node.

fix [#30925] successful import of keyconfig dependant on current object context?

revert r34885,

The hack was to fix poselib UI but is REALLY BAD - don't modify properties when accessing them.

This bug must be fixed some other way.

Fix part of #30934: save as image in image editor did not set proper defaults
for options like compression.

Fix #30929: cycles rendering of object with scale 0 on some axis did not work
correct with instancing.

Actually such object will not work in many places, e.g. transforming vertices
in edit mode doesn't work and textures will be misapplied in Blender Internal,
so these should be avoided.

bmesh todo: vertex dirtmap now working again.

also renamed Polygon helper property from 'loops' to loop_indices

- startup.blend's temp dir was pointing to sergeys user dir, now point to /tmp
- fix error in ctodata.py (was adding dummy bit)
- make UV hide from last commit more readable.

set executable option and some minor changes to ctodata/datatoc

fix [#30923] Hide Unselected in the UV/Image editor does nothing

bmesh - UV editor: check if faces are visible before hiding them (was done before bmesh merge).

style cleanup: uv editor
