Previously it wasn't clear what it was supposed to be doing, or what was
required for it to work.
TODO: figure out why the operator redo settings panel won't work. The workflow
here is still a bit clunky.
Also generate rigid body constraint types in py bullet code from RNA enum values (simpler than having to sync the code when something is changed here!).
Side note: RNA API about icons still needs to expose icons for enum values, and conversion funcs between icon_name and icon_value!
Now all add/remove operators for rigid body objects and constraints
automatically add objects to the appropriate groups and create groups if they
don't exist yet.
This makes handling rigid bodies easier but doesn't take away functionality.
If users want to handle groups manually they just need to create them before
adding any objects.
The previous behaviour was confusing and was even considered to be a bug since
clicking on rigid body in the physics tab seemed to do nothing.
Behaves like the generic constraint but has optional spring on each axis.
TODO: Add option to set rest length.
Patch by Markus Kasten (markus111), thanks!
Constraints connect two rigid bodies.
Depending on which constraint is used different degrees of freedom
are limited, e.g. a hinge constraint only allows the objects to rotate
around a common axis.
Constraints are implemented as individual objects and bahave similar to
rigid bodies in terms of adding/removing/validating.
The position and orientation of the constraint object is the pivot point
of the constraint.
Constraints have their own group in the rigid body world.
To make connecting rigid bodies easier, there is a "Connect" operator that
creates an empty objects with a rigid body constraint connecting the selected
objects to active.
Currently the following constraints are implemented:
* Fixed
* Point
* Hinge
* Slider
* Piston
* Generic
Note: constraint limits aren't animatable yet).
Add operators to add/remove rigid body world and objects.
Add UI scripts.
The rigid body simulation works on scene level and overrides the
position/orientation of rigid bodies when active.
It does not deform meshes or generate data so there is no modifier.
Usage:
* Add rigid body world in the scene tab
* Create a group
* Add objects to the group
* Assign group to the rigid body world
* Play animation
For convenience the rigid body tools operators in the tools panel of the 3d view
will add a world, group and add objects to the group automatically so you only have
to press one button to add/remove rigid bodies to the simulation.

add Ctrl+Shift+Tab shortcut for selecting snap type to the UV editor too.
also added icon drawing to WM_OT_context_menu_enum() so it gets the icons from the enum to draw them in the menu.
- add sequence.update(data=False) function.
- made some sequence vars editable.
- correct some comments.
also rename rna function sequence.getStripElem() --> strip_elem_from_frame()
bake_action tries to make kind of a 'visual keying'... On one side, this is rather stupid when you keep constraints (in this case, keying actual loc/rot/scale transforms, i.e. matrix_basis, is enough, doing more would lead to unexpected behavior with some constraints). On the other one, making a good visual keying of bones is *really* tricky, so now using the new object's convert_space() func to compute that (when the user chooses to remove the constraints).
Incidentally, this greatly simplifies the code of bake_action!
