Removed the now redundant "Read" toggle from cache libraries.

At this point the reading is toggled on the side of group duplicators.

Move 'Update Views' to the _ex panel, and fix crash on update routine

Merge remote-tracking branch 'origin/master' into multiview

Removed the explicit duplicache rebuild operator.

The cache is now updated on frame changes automatically, the operator
should no longer be needed.

Removed unused deprecated functions for cache library.

Sanity check for dupligroup caching functions.

Merge branch 'asset-experiments' into asset-engine

Conflicts:

Use a new flag in duplicator objects to enable cache reading and avoid
unnecessary dependencies.

This flag will replace the current "read" mode on cache libraries.

Beside enabling cache reading, it also disables the current "fake"
dependencies between duplicators and their group objects. This is
exploiting the layer visibility mechanism in depsgraph to ensure that
animated group objects get evaluated when used by a visible duplicator,
even when they are not themselves visible. These dependencies cause
group object updates even if the duplicator is using cached results.
To avoid this unnecessary overhead and make caching worthwhile we
rebuild depsgraph without these relations when using the cache instead.

Point submodules to 2.74-rc2

Fix broken 'sort by type' in filebrowser.

Also, take advantage of blentype stored in entries now,
this greatly simplifies (and make quicker) that sorting
for blendlib items!

Add a 'comment' field to listdir revisions.

Also, make clear tags are only informative here.

Reason is, if the project is a success, we have to think big and
imagine asset engines managing catalogs of tens or hundreds of thousands
of entries (web ones e.g.), we cannot hold list of those in filebrowser!
So most of filetring will be 'deffered' to asset-engine.

We'll also probably have to implement a 'chunck listing' behavior
(to only list at most n entries in a row), for same reasons.

This will make things slightly more complicated :|

Small cleanup (int to bool)

From review: left over from Dr. Epilepsy mode removal

From review: better error message when active camera is not multi-view

Fallback to the zero ibuf, not the last one

Merge branch 'master' into asset-experiments

Fix an incorrect assert in lnor code.

There is one case where we do can have only two edges for two loops...

Refer to Task 43975: Deleting a Shapekey can break the relative pointers

This patch would reassign the relative of all keyblocks to the relative
of the deleted keyblock. And it fixes the misalignement of the index values
after the keyblock is deleted.
