Removed unused line.

Unlink and cleanup functions when objects or the cached group get
unlinked or changed.

Make sure cache item pointers are lib-linked correctly.

Name string construction for cache items, to use as a unique identifier
in the cache library.

Draw some UI buttons for all the current cache item types.

Updated hash table for lookup of enabled cache items and added basic
UI support.

Improved collections in RNA for looping over potential caching items
in the object group.

Define a collection of "object_caches" in the CacheLibrary RNA for
iterating over all objects eligible for caching in the group.

This allows for nested dupligroup instances as well. All objects that
are instantiated at least once by any group can be included in the
respective cache, but get represented only once because the cached data
is the same anyway.

Link main CacheLibrary pointers in readfile.

Simplified cache item path description, based on plain ID blocks with
subtype/index.

This omits possible instancing and recursion by dupli groups, but since
the data of instances is always the same in Blender at this point, there
is little need to take them into account for caching.

At some point in the future it may become desirable to store full dupli
hierarchies in the cache, but it doesn't make sense to try to design a
fully-fledged path descriptor for this hypothetical case now.

BKE functions for managing cache content based on a group.

This uses a complete hierarchy of group instances, based on a path
hierarchy (object names).

Putting

Simple cache manager panel UI in the scene buttons.

This is mostly a simple and unintrusive placeholder to have some way of
making caches accessible, but needs some more thought.

Group pointer property for cache libraries to associate them with an
object group.

This is somewhat experimental, eventually we may want to link to Objects
instead, or allow multiple cache targets for the same cache, etc.

Missing include.

Removed meaningless comment.

`New` operator for adding cache libraries.

New ID datablock 'CacheLibrary', for managing physical cache archives
and files.

At it's core this is just a file path, but many different cache users
may refer to this, so having a dedicated ID block helps. It can be
compared to Image datablocks, which also primarily are used for data
on storage, but can be packed with the blend file, and carry some
additional information that would be cumbersome to keep sync'ed
otherwise.

The name 'CacheLibrary' deliberately resembles the 'Library' datablock:
just as a Library stores ID blocks in a physical file, a CacheLibrary
stores cached data (in Alembic HDF5/Ogawa or other formats).

Fix for remaining PointCache references in the alembic code.

Now, for the time being, uses a simple relative "//blendcache/" folder
path again. This will be adressed later.

PointCache modifier to act as a terminator in modifier stacks.

When writing DerivedMesh data, the modifier result at the point of the
modifier will be used for writing to the cache. If this modifier is not
used the derivedFinal mesh is used instead.
