updated md2 exporter from 0.17.1 to 0.17.5
(not my work, asume Bob Holcomb's)
some extra features triangualte on export, usibility tweaks and try fan, strip improveemnts.

Made this script motherball aware-
Metaballs that are numbered are not included - only the un-numbered motherball when getting the mesh data for objects.

- fixed bug #4517:
there was a wrong divisor for memory estimate

Another fix based on venomgfx fraka .blend:

In december, when testing material layering, I've removed the check that
prevented specular and diffuse to become negative, this because it could
work nice for layering.

However, this breaks quite some cases too. For example negative lamps are
only used to cancel out other lights in same material, and should not give
negative (invisible!) peaks that work on a node system. Same goes for
negative diffuse from AO 'subtract' mode.

In fraka the error happened for AO on a translucent material. The inside
of the mesh got a negative AO, cancelling out the positive AO on the
outside.

Anyhoo; this commits ensures that a 'shade_lamp_loop' call will never
return negative values again!

- bug fix for #4606,
too small size of base MetaBall object caused infinitive loop

added list2MeshWeight and meshWeight2List - faster then the dict equivilents and better in some cases.
Speedup for bpymesh_redux (poly reducer) with reducing vertex weights. use list2MeshWeight and meshWeight2List.

renamed vertex gradient files

Removed reload()'s
- 3ds_import.py
- mesh_cleanup.py
- mesh_poly_reduce.py
- vertexpaint_selfshadow_ao.py

Cosmetic change: the FFMPEG options for HD sound/movie are hidden behind
the #ifdef now, so it won't arise questionmarks in releases.

Bugfix in NMesh:
- Setting hasFaceUV to false didn't work correct, missing braces in
define.

Fix for bug #4600:
- Array modifier crash with vertex merging. There was a missing check
for a vertex being merged with a vertex that was merged with itself.

Removed another Malloc from renderwindow callbacks (used while render).

BTW this is most likely bugfix for 2 reports, will verify tomorrow.
BTW2 all credits go to Andrea!

attempt to fix crashes (reported under Linux)related to OpenGL extension queries.
seems to be a known issue, combo of pthreads, dlopen and libGL cannot call dlclose !?!
Let's cross the fingers this works...

Two fixes, venomgfx Fraka bird test!

- AO "Use Distances" can not use 'sky texture' for colors, that bug was
fixed in UI (prevent settings to combine), but better also gets fixed
on reading files.

- Backbuf render, when not existed, didn't initialize backdrop color to 0.

Replacing screen_swapbuffers() with a direct swapbuffers() call during
progress of rendering. This prevents calling anything else but the
swap itself.

Might fix render memory issue in Windows.

== FFMPEG ==

Rewrote the video seek code again. This time it is a _lot_ simpler and a lot
better.

For those interested: instead of letting ffmpeg choose the right final
position, we let it preseek (maybe to I-frame in the rare case, that is
implemented) and then scan for the correct frame on DTS basis by hand.

We therefor only have to seek once and remove all those frame-jumping
jerkiness, people noticed in the same step.

Tested with msmpeg, hd-mpeg2 and DV.

updated raw import/export nice error messages, optimized with LC's removed meshtools depencancy, use Mesh instead of NMesh

===Python API===
Bugfix #4369. Patch provided by Alberto Torres Ruiz (thanks) which
fixes a bug in EditBone_getRoll(). Thanks!

[ #4585 ] - fix for reading videoscape files
- yet again a file path that was too short ;)

Very minor warning fix for gcc4 in these 2 files (unitialized array)

===Python API===
Bugfig #4527: add more robust bitfield checking for Mesh.mface.flags;
unconfirmed bug report that an exception was caused with RC3a that could
not be reproduced. It was possible that a pre 2.42 .blend might have
some additional flag bits set that would have caused an error.
