New: CrazySpace [tm] correction

When Modifiers are used in Edit Mode to show the deformed result for
editing, all actual coordinates Blender works with are still the ones from
the original Cage. You can notice that with the Transform Widget or
helper lines while transforming.

Even worse, the actual transformations still happened on the original Cage
as well, making it very hard to edit. That caused the feature to be named
"CrazySpace" (baptized by Andy, afaik?).

This commit calculates the deformation transformation per vertex, and
inverse corrects it, so it's more intuitive editing this way.

Unfortunately all the deformation features of Blender don't use matrices
for defining deform, so the existing code cannot be re-used to retrieve
the correct deformation matrix per vertex. The solution I found is based
on calculating per face the transformation based on its first 3 vertices,
and store this transformation averaged in the face's vertices.
The solution can also only work on entire faces, because the full deform
can only be retrieved using 3 vertices. (using 2 vertices will miss edge-
aligned rotation, using 1 vertex can only retrieve translation).

By deriving the deformations per face, small errors will still happen,
especially on very low-poly Meshes with extreme deformations.

The only alternative I know now, is providing each vertex in
a mesh with 2 extreme small tangent vectors, which get deformed using the
existing code as well. That will mess up the existing deformation code too
much though, this solution has the benefit it works with each deform we can
up with later too.

Last note about CrazySpace: it can only be used to tweak Meshes. Do not
even try to add vertices, extrude, or duplicate. Probably we should disable
this... but preventing user errors isn't always power-user-friendly, eh. :)

fix access of pointer before its assigned

FIX: BLI_makestringcode called with bad pointer mainl->curlib
Moved call to before blo_join_main where pointer gets killed.
Otherwise Blender crashed when appending a file and selecting
relative filenames.

Bugfix #3231

Constraint Ipos didnt work when the bone/channel had no Action Ipo...
just had to move a line of code. :)

New; Rotation Constraint allows to only copy X,Y,Z axis rotations.

Note this is based on eulers, so might give the common issues. :)
For most cases it goes fine though, especially with only 1 axis constraint.

Bugfix #3232

When a file was loaded with curves in invisible layers, the displists
were not created.

Bugfix; appending with using relative paths made all dynamic links from
other libraries local.

Also added some securities in the temporal 'sync pose' testing code. It now
asks with a menu to confirm the object to be replaced too. Later more!

updated elbeem project for new / removed files

getMarked return change to dict
.

Fix for when knife tool (with path setting) is terminated with ctrl-Enter.
Also, updated the little helper line on the status bar to indicate that
terminating with ctrl-Enter leaves only the verts on the cut line
selected.

Johnny: Please review.

First commit, for test, for using Library files for synchronizing partial
data. This functionality is going to be in Outliner, for now only use
for testing while consulting me. :)

Usage: New option in SHIFT+F1 append window, "Sync Pose". When pressed, you
can append/load an *Object* of type Armature, this then replaces its
Armature and Pose with the selected Objects. After that it deletes the
appended object.

Note: it currently appends also Objects when used in Pose Constraints...

Subdivide recode assistance!

- Added subdivide sck upport for vertex groups
- Brought back subdivide-smooth, but it doesn't work as good as before yet,
it used to catch an exception for subdividing the middle vertex of a quad,
with edge-based subdivide it's not that simple. Will check later.
- made "number of cuts" a static variable, so it doesn't jump back to 2
all the time

Coder level notes:

- removed the old subdivide code (yay, over 30k code less!)
- did some minor layout cleanups in the new code (just consistant syntax)
- removed redundant code parts, to enable smooth & vgroup subdiv
- subdivide smooth can do multiple cuts too, but i like to see that only
as option when our smooth formula is good!

Compliment:

I think Johnny really made comprehensible design and nice code here. Was a
joy to work with. :)

fix for bug #3193, winmat was not calculated properly because of
some previously uninitialized parameters.

Only restructured code:
- added Hos fixes
- split up solver into 3 cpp files (as suggested by jonathan)
- de-inlined function that caused gcc33 to use >1GB of memory

-Bugfix #3254: Ipo.addCurve() didn't check if curve already existed before
creating (reported by Toni)

More bugfixing related to #3149:
Drawing of rotation limits and IK solving was wrong with pose mode
bone offsets.

Also added proper modifier stack update after uv unwrap and lscm.

cleaning up
- removed euler branch in favor for a 'better solver to come'
- removed some debug vars from lattices
- removed some garbage related to 'borrowing' collision from particles
note SB collision is completly decoupled from particle stuff to allow
: 1. SB collision targets can be 'anything evaluated by modifier stack' but won't be subsurfed (for performace reasons / possible though / see comment in code)
: 2. SB <-> SB collisions
: 3. ( 1. implies that SB collision targets may be animated, hooked, curve deformed , .. ! )

Fix for correct handling of relative filenames.
Now relative filenames that are not below the .blend file
in the directory hierarchy can be used.

CAUTION:
The relative filenames are not updated if the blend file
is moved to another dir or saved into another dir (save as)
We will rely on the smartness of the users for this.

my first official commit - thanks Ton!

Bugfix #3242

Ipo WIndow, "Make single user" button crashed. Forgot to recode 2 weeks ago

Made it so that number of editmode unsteps can successfully be set to zero.
