Fixed bug #5219, Undo doesn't work in Sculpt mode when modifiers are applied

Just added a missing call to update the active object.

Removed redundant variable declaration in my previous commit.

made mesh.getFromObject() accept a python object as well as the object name.
accepting the name only was causing big problems when exporting library data, because duplicate names are possible the wrong data was exporting.

Tiny usability fix:

Until now, pressing ALT-A in a sequencer space without image preview was
pretty useless: It only showed an advancing green frame pointer :)

Now, if you press ALT-A over a sequencer space with strips, it will also
animate all sequence previews. So, no need to press SHIFT-ALT-A in that
situation anymore.

Of course, pressing ALT-A over a preview will still only play that preview.

Windows other than sequencer windows remain unaffected by this commit.

Two tiny compositor annoyances;

- Image Node: after loading new file it didn't update the header name
- File-out Node: header color suggested there was only 1 'active', which
it isn't.

Fix for bug #5220: crash on edgeloop delete.

Bugfix 5182

Mist option and "Ray Transp" didn't work together yet. Transparency
during tracing should not be influenced with mist though (as is for
Ztransp), so for this case an extra color blending after raytrace is
added. Still pretty primitive... mostly because mist isn't volumetric
in Blender at all... just an alpha trick.

Bugfix #5217

Call to refresh Image Icon on load should not be done for background
renders... crashed blender then.

Previous commit (Smooth Ipo) was indeed not too useful. I've
rewritten the code (less code now) so that it is more useful, and
doesn't just duplicate the functionality of another feature.

Now, IPO smooth works only on the selected keyframes in
selected frames. It finds the average value of all the selected
keyframes, and finds the halfway point between each keyframe
value and this average value. Handles are also automatically set
to 'aligned'.

== IPO Editor Tools ==

* IPO Curve Smoothing:
This new tool smoothes (i.e. resets the adjusts) the handles on selected
ipo curves in ipo editor. The core code is based upon a python script
that used to do this (author unknown).

- Available from menus
- Hotkey Shift O
- Only available from ipo editor

If the usefulness of this tool is limited (adding bloat), I will consider removing it.

==== scons ====
- cleanup for wintab library headers
- properly define BF_WINTAB and BF_WINTAB_INC

Just a few fixes to the indention of some functions (purely cosmetic code changes)

Set the default material preview type to 'sphere' for newly added materials.

Removed erroneous switch to the front buffer when reading depth values in sculptmode and retopo.

updating Bullet 2.x with latest changes. The integration + C-API will follow at some stage.

- compile fix for msvc 6 which doesn't declare M_PI at all it seems.

bugfix
crash with duplicated softbodies
in copy_softbody() scratch pointer was not initialized to NULL in copy
did not know that function exists at all

Ooops, previous commit of mine forgot to commit the .h file.

compile fix for MSVC compiler.
- math.h doesn't include #define M_PI by default (_USE_MATH_DEFINES needs to be defined)

msvc6 adding DNA_customdata_types.h to project
