- made the console banner printing function into a python operator (includes sys.version)
- added 'C' into the consoles default namespace for convenience
* #19819: 'Select' operator for Hooks was crashing when Hooks didn't have any vertices assigned yet
* Default twist resolution mode for curves is now 'Minimise'. This seems to work better for Curve Deforms and other purposes. Can be changed if other ways are better after some more testing.
* Spline IK now has more options for controlling how the x and z axis scaling is determined. There is now a choice between using the radius of the curve, the x+z scaling from the bones, or no scaling (default). This does break old files a bit, but this is to have a more stable base for later.
Depgraph update was commented out in undo system because of globals, restored this with new context/id-based depgraph
* Fix in UV editor UV menu
* Slightly nicer default names for adding forcefields with Add menu
- split into 2 operators: object.make_links_data() & object.make_links_scene since they are quite different.
- added reusable functions RNA_group_itemf & RNA_scene_itemf which can be used for any operator that takes ID data (easy to add more types Mesh, Text etc)
- DummyRNA_NULL_items for dynamic items so each operator need not define its own empty enum.
1) "Even Divisions" - This option ignores the length of bones when considering how they should fit along the curve. This is useful for getting a smoother curve fit without having to worry about getting the bone lengths spot on. By default, this is disabled.
2) "Keep Max Length" - This option prevents the bone chain from extending past its natural length when the spline is stretched beyond that length. When the spline length is substatially shorter though, this bones get scaled to zero; making this option possibly useful for doing "growing tips".
This is essentially a 'no scale' option, although the behaviour when the curve is shorter is really a compromise since the curve cannot be accurately satisfied + left intact without some scaling being applied due to the way this works.
3) "Radius to Thickness" - The average radius of the spline between at the head+tail of each bone determines the x+z scaling of the bone.
At last, this commit introduces the Spline IK Constraint to Blender. Spline IK is a constraint that makes n bones follow the shape of a specified curve.
Simply add a chain of bones, add a curve, add a Spline IK Constraint to the tip bone and set the number of bones in the chain to make it work. Or, try the following test file:

I've implemented this in a similar way to how standard IK solvers are done. However, this code is currently not an IK plugin, since I imagine that it would be useful to be able to combine the 2 types of IK. This can be easily changed though :)
Finally, a few notes on what to expect still:
* Constraint blending currently doesn't affect this. Getting that to work correctly will take a bit more work still.
* Options for not affecting the root joint (to make it easier to attach the chain to a stump or whatever), and non-uniform scaling options have yet to be added. I've marked the places where they can be added though
* Control over the twisting of the chain still needs investigation.
Have fun!
Contributors list isnt used much in our C code so probably its easier if people just use svn blame for this.
Can change if this isnt acceptable but I guessed people didnt care so much since most scripts had no header.

This adds:
* "Show All Layers" to the View3d -> View menu
* "Center Cursor and View All" and "Align
Active Camera to View" to the align view submenu.
This is effectively a C-port of Nathan Vegdahl's "No Twist" TrackTo PyConstraint, and has been added as a separate type of constraint to be consistent with the existing constraints (Locked Track, and Track To).
In general, this works considerably better than the existing "Track To" constraint, since it works by determining the smallest rotation necessary to get the current orientation of the owner to an orientation which would be tracking the target. It is also a much more straightforward approach than the weird old method the old Track To uses.
I've made a few tweaks to the code to deal with the (hopefully rare) cases where the target and the constrained are coincident. These don't appear to cause too much trouble in general.
TODO:
- Probably the naming of the constraints will change, to better convey their purposes. Naming suggestions welcome.
