Changes from reviewer (Dalai Felinto):
* Code style (replace tabs with spaces).
* Return OPERATOR_CANCELLED if no a single object get through.

"Blend from Shape" lists keys from active object and applies to all selected
objects that have keys with a matching name.
Changes from reviewer (Dalai Felinto):
* Code Style.
* Move Object **objects after sanity check to prevent leak when
returning OPERATOR_CANCELLED.
* Skip objects that have no selected vertex.
* Fixed existent comments code-style: Since we are changing the indentation of
these lines, may as well correct this as well.

Since D3284 was inactive for a long time, I figured I could finish this.
This revision also gives warning when there are no selected faces or when
selected faces are invalid.
Changes from reviewer (Dalai Felinto) :
* Code style
* Fix checking for ngons (BM_ITER_MESH is a for loop, you need to break from it
before continuing the object iteration loop).

This implements angular bending springs for cloth simulation. This also
adds shearing springs for n-gons.
This angular spring implementation does not include Jacobian matrices,
as the springs can exist between polygons of different vertex counts,
rendering their relationships asymmetrical, and thus impossible to solve
with the current implementation. This means that the bending component
is solved explicitly. However, this is usually not a big problem, as
bending springs contribute less to instability than structural springs.
The the old linear bending model can still be used, and is the default for
existing files, to keep compatibility. However, the new angular bending
model is the default for any new simulation.
This commit makes small breaking changes, in that shearing springs are
now created on n-gons (also in linear bending mode), while n-gons were
previously ignored.

This separates cloth stiffness and damping forces into tension,
compression, and shearing components, allowing more control over the
cloth behaviour.
This also adds a bending model selector (although the new bending model
itself is not implemented in this commit). This is because some of the
features implemented here only make sense within the new bending model,
while the old model is kept for compatibility.
This commit makes non-breaking changes, and thus maintains full
compatibility with existing simulations.

MASS unit was already implemented for the C api. Only making sure it is
accessible in the python api. Also added 'CAMERA' to the documentation as a valid option.
I'm using a different shading group for the active text box and the others.
This way I can assign different colors to them.
The alternative would be to create a new `shgroup_dynlines_dashed_flat_color`,
but I find this overkill for such a simple use case.
The statement that PBVH needs to keep track of CCGDM is wrong, PBVH itself
does not care about CCGDM at all, and it's weird for it to carry on this
beast so others can access.
Even more, nobody will actually caring about CCGDM itself, all the usages
were checking whether there is CCGDM or not. This is as good as simply
checking PBVH type.
Tested with an original report T53551 and everything is still stable.
