knife_project_v3 can call ED_view3d_project_float directly without having its own check for ortho

In the node space context update function: Properly clear the snode->edittree pointer when no snode->nodetree is active. This would lead to crash in operators when switching from an existing node tree, since the usual poll function only tests for the edittree.

Fixes bug #29566.

Fix #29516: Twist brush giving crazy results

- Rotation now happens around initial stroke location rather than around scene origin
- Added slider for rotation strength which helps in cases only few rotation is needed
to be to increase the precision of such strokes

Fixed for movieclips tag function which was tagging wrong list

Pointed out by Lockal, thanks!

Bugfix [#29567] Second Hook Modifier fails on Curve Object

This was broken in r.42515. In particular, rigs with Spline IK would break,
since they often use curves with hook modifiers controlling the control-points
of those curves.

Compile fix for r.42546 typo

disabling DM_calc_auto_bump_scale() until after release

picky edits & regen man page

fix for error in bpy_extras.image_utils.load_image() when the image file exists but cant be read (wrong permissions for eg).

verify existence of dm

fixes scale on derivative maps

fix for bpy_extras.image_utils.load_image() making a placeholder image when passed a path in bytes.
made OBJ import fail when the image was missing.

check for weights outside of 0-1 range when validating weights

Fix #29558: Selecting similar edges doesn't work

Return OPERATOR_FINISHED from select grouped operator in any case so
even if nothing were selected operator would be registered in redo panel
and threshold can be adjusted there.

Fix for recent rna rename of global to use_global

Fix for select similar vertices operator: it's exec used to return selection count
instead of OPERATOR_* return values which used to confuse operators system.

Mesh drawing optimization and fixes:

- Pass MFace, MTface and OrigIndex arrays via userData to compareDrawParams callback
rather than looking up for this layers for each face
- This allowed to avoid massing DM to compare callback which seems like a bad-level pass
- Fixed crashes on some video cards when assigning different materials to different
faces in edit mode. Both of intel and nvidia cards in my laptop were affected by
this error

global is python keyword so cant use as operator argument,
also ran operator cheat sheet and made sure no syntax errors.

+ minor pep8 edits.

Merging r42482 through r42532 from trunk into soc-2011-tomato
