Improved damping calculation.

Now actually uses the damping substeps setting. Damping happens as an
additional step _after_ the main force calculations. Note that it
updates the next.velocity based on the next.velocity itself, unlike the
actual semi-implicit Euler step, which works with the previous velocity.
This makes damping much more accurate by letting it work with the
changed velocities right away before they introduce too much energy into
the system.

attempt to create sub-objects by referencing a group of "child" objects within the modifier, but customdata transfer (like textures) wont work for some reason

Run sim from timeline, without Bake button

Minor changes/cleanup in BKE_mesh_normals_loop_split, and use a bitmap for sharp_verts.

There is no real difference between a plain bool array and bitmap for sharp_verts,
and this should save quite a bit of mem with heavy models.

Simplify/fix code to set custom split normals.

We might lose a (very tiny) bit of performances in some cases, but this is not
a critical area, more important to have a simple and working code. Also,
this func no longer modifies given array of custom normals! And hopefully
weights handling is now correct in all cases.

Cleanup of integrator functions, to clarify which values are calculated
at which stage in the process.

This is a preparation for damping calculation fixes.
