[#8784] orbiting around selection bug + a few kind of a must features (partial fix)
As suggested by Ton, keep last center and use that when nothing selected.
I don't really like it though as it wouldn't work ok when changing scene or when using a different 3D view and is somewhat non trivial to explain (it's not the last selection, it's the last used orbiting center).
needed to add a small value to the baking distance for it to include faces of that distance (maybe should make this happen from the user interface too)

Extension node attributes are now read and stored as ID
props for the following Node types:
-Object Nodes
-Group Nodes
-LOD Nodes
-DOF Nodes
-Inline Light Point Nodes
The extension data is written back out on export.
Note that this commit only adds support for attribute extensions.
Completely new node types via the extension record are still
unsupported.
Bug might have actually caused more issues, there were some assumptions
that ParticleCacheKey and ParticleKey structs had members in the same order,
but the rotation was in a different place.
----------
Bugfix #8615: NMesh.update() did not check if faces had less than 3 vertices, so would create bogus faces.
Also discovered in the process that documentation and error message for Mesh.assignVertsToGroup() was wrong.
active face drawing didnt always work since it used the last selected element for drawing.
moved stipple into glutil.c rather then using 128 bytes in the stack for each stipple draw.
Replaced the use of remove doubles with some new custom 'face welding'
code that wil clean up meshes on import.This will not remove any faces
or do any edge collapse and so is a more suitable method of cleaning
up imported meshes. This same code could potentially be of use when
importing other formats as well (such as DXF...)
* Bugfix #8599d:
When using the ChildOf constraint on bones without parents, with cyclic-offset in action the effect of the cyclic-offset was applied twice. Added a bone option to make the effect of cyclic-offset not be applied to rootbones which have the option 'enabled'.
In the UI, this is presented in the opposite way. It is represented by the 'Offs' button beside the parent-bone selector in the Armature Bones panel when in EditMode.
* Head/Tail setting and Constraint Channels:
Added back in checks to see if the head/tail IPO-curves for Constraint Channels can get applied for the target constraint. I had removed these when applying the patch, but I'd overlooked the fact that users could add an IPO-curve for this from the IPO-editor, potentially mucking up the behaviour of some constraints.
a few times peach guys have had the play button fail with "stack smash" warnings in the terminal and play button not working.
This fixes a reproducible crash where blender would segfault when pressing play on long filenames, and hopefully fixes odd user reports where pressing play quits X11 or reboots their system.
Resizing two text windows stacked one over the other, crashed in certain cases (i.e. when dragging the border between them down to the header of the bottom one). Was caused by division by zero, resulting in a SIGFPE (floating point exception).
This appears to be a long-standing bug, and it only affected the Follow-Path constraint as it was the only one which was dependant on time-based changes. An oversight in the depsgraph code meant that Follow-Path constraints on armature bones were not evaluated, unless there was an Action or some NLA-Strips for that armature.
I've added a new flag to pose->flag (POSE_CONSTRAINTS_TIMEDEPEND) which only gets set/cleared by update_pose_constraint_flags. This flag indicates that the depsgraph needs to do an update for such cases, and will require going in/out of EditMode to set this for old files.
It's been implemented as such to avoid having costly searches when trying to run animations realtime (as is done for modifiers).
