added global keep shards mode for cutter groups

fixes: activating clusters via percentage, add meshisland id as name in fracture too, load crash fix

Cleanup: Indentation

Cycles: Add overall timing log to SVNShaderManager

Fix missing 'prop_required' flags in some ID RNA funcs.

Not critical, but would rather have this in 2.78 (for API doc reasons mostly).

Cycles: Deduplicate QBVH node packing across BVH build and refit

ui cleanup in fluid quality and general fluid tab

Fix/Workaround T49297: Crash related to custom data draw (Blender with ASAN)

Root of the issue is that active render index became wrong. This is the actual
thing to be fixed, but as usual this is quite tricky to reproduce. Since such
bad situation might have happened more and fix isn't really difficult or
intruisive let's avoid crash for now.

Can be revisited once we figure out root of the issue.

Nice for 2.78 release.

Fix T49299: Removing offset object in modifiers doesn't update mesh.

Own fault in new ID management work, thought rebuild the DAG itself was
enough to actually update whole scene, but we actually need to tag datablocks
for update as well, when we change (or remove) one of their ID pointers...

Smoke viewport: remove dead code.

OCD commit, but cleans the code a bit:
- the first `if 0` block was supposed to draw collision objects but is
vastly outdated as most of the SmokeCollisionSettings member variables
were removed a few years ago and collision objects are drawn like other
objects anyway. Also it was committed already commented out back in
2009.
- the second `if 0` block was doing pretty much the same thing as the
few lines above it.

Alembic streaming: initial support to interpolate data between frames.

Pretty self-explanatory, allows to get some slow motion type of playback
and animations.

Alembic: add option to triangulate meshes upon export.
