Orange:
So... now I understand file reading and libraries again, I couldn't leave
it to do a nice optimize step. This commit introduces bsearch() for finding
the elements in the pointer table, while reconstructing links. Tests reveil
a speedup of a factor 2-5 on complex scenes. And since undo uses same
system, quite nice in general!

(Note; speedup sometimes can't be noticed, when a lot of subsurfs or other
displaylists need to be generated.)

Disabled reading Groups from bf-blender. There was old rudimentary code
for Groups in official release still, which will give very bad results when
loading an Orange branch file with bf-blender, save over, and read back
in Orange branch.

Now, reading files with Groups in bf-blender will just completely ignore
them (not read nor save). That's destructive, but normal behaviour and
stable.

Scripts:

- Jean-Baptiste Perin updated his bvh to armatures script to use the new
armature module.
- Johnny Matthews (guitargeek) contributed "Shape Widget Wizard". (Moved
it to the Animation menu in Scripts win)
- Benoit Foucque (dienben) contributed "Blender Lip Synchro".

Thanks to the three authors!

Made Ctrl+RMB on an image in the oops view, activates images in the UV/Image window.
Faster way to flick through images.

Fixed some warnings from GetCurrent, remaining warnings seem to have no obvious solution
attr = Py_True; // Image.c:1107: warning: dereferencing type-punned pointer will break strict-aliasing rules

Scripts:
- added import and export scripts for 3ds and md2 (Quake 2) models
contributed by author Bob Holcomb. Thanks!
- updated ac3d importer to be more forgiving and exporter to get rid of
deprecated call.

More additions and possibly fixes to come.

Note: we're forming a group to take care of importers and exporters and
improve the situation as a whole in Blender. Discussions should happen
at the bf-scripts-dev mailing list:
http://projects.blender.org/mailman/listinfo/bf-scripts-dev

Thanks Tom Musgrove (LetterRip) for helping a lot with scripts.

(Orange branch)
Phew... a whole day revision of library linking system... there was a bug
when objects got linked, then removed, and then linked via a group... this
was a weak part in the library system, when data is used both "direct"
(like local object is linked to scene) and "indirect" (when group from a
library has same object).

The crucial fixes are easier to find by reading the diff... this system
is just braincrunching complex! Just as note to self then;
- ID_ID oldmap-lookups are now protected
- removed adding oldmap lookups for already read data

For Matt & Basse: you can do a very good cleanup of old files by putting
the "rt" button on 127, and then save file. This will skip writing any
reference to library data in the file, with exception of group links.
Reload a file might give some link errors, but a 2nd save and load then
should result in a clean file.

Another merger of Orange branch with bf-blender, it has important fixes.

Three fixes;

- On file reading, a check is added to see if a Pose has channels to
missing bones. Poses are supposed to match an Armature completely.
(Thanks for crash file, Johnny!... but how did you do it!)

- Own collection: added depsgraph update on setting all layers (with the
ACCENTGRAVEKEY). This also could potentially crash with modifiers

- Renamed Xkey menu in NLA to more properly tell what it does. :)

Orange; added a depsgraph update tag for the case a Group is being animated
with NLA, whilst the "NLA target" has no action or nlastrips itself.

BPython:
- malformed nmeshes could crash Blender with a sigsegv. Related to old
behavior that accepted "faces" with one or two verts.
- removing unused var (store_edges) + doc update.

orange: added Object.insertPoseKey to continue with the attempt to make nla/path walkcycle baking to actions

Orange; Magical Group relink option. :)

This is the case:

- Empty has Group duplicator
- Empty has NLA strips to animate the group

On linking the Empty to another group (with button in ObjectButtons), it
checks for the current strips in NLA, and tries to find the proper objects
in the new Group, based on name matches.
If not found, it sets the strip-objects to zero.

Orange: On adding constraints, names are now unique per object/bone, this
prevents confusing situations when adding constraint ipos.

Wednesday merger of Orange branch and bf-blender

Commit with fix for ActionStrip "Hold" missed two crucial features;
- if repeat is set on exact integer values, it jumped to first position
- code was missing the action start offset

Orange: added proper stringcopy for creating/finding pose and action-
channels. This for python api development here... :)

Orange: more relative path code cleanup. Introduced a new call in the
blenlib to correctly convert a relative path to a clean new path:

BLI_cleanup_dir(const char *relabase, char *name);

Only works for directories now.

Orange; more relative path messing... the functions in Blender for it
don't work consistant;

BLI_makestringcode()
This one works correct for paths that go up; it then makes a relative
path like : //../lib/file.blend

BLI_convertstringcode()
This one delivers different paths when it expands, the previous case
will just append the relative path, like /work/project/../lib/file.blend.
That string cannot be compared with the original... which happened to find
out if a library was read already.

Solution for now is that only the relative paths are compared, but it
won't work if multiple relative levels are used... like for libraries
that link recursive. To solve that, the entire 'relative' concept has to
be redesigned.

Added
Image.New(name, w,h,depth)
Image.start- for animtex
Image.end - for animtex
Image.speed - for animtex
Image.packed - read only bool
