Layer group support

Adding a new group inserts all selected layers/layer-groups in the new one. Things like "add to group" are not supported yet.
Groups have a folder icon, their members are drawn with indentation.

added phitemp grid to mantaflow script (for blender to use for liquid mesh map)

Fix curve using editnurbs in object mode.

Depsgraph: Some more simplification of object destruction

Depsgraph: Make sure memory reports stays all grouped

Depsgraph: Simplify some destructors

Merge branch 'master' into alembic_basic_io

Depsgraph: Add some utility macro to avoid long typecasts

Initial support to import hair systems.

For the time being, hair are read as curves since this is how alembic
stores them. And since there is no real way to know if an ICurves object
exported from another software is a hair system or not, it will probably
stay like so.

Depsgraph: Remove unordered set header

Once again it became unused and obsolete.

Fix crash when exporting a hair system.

Crash was due to accessing hair data from another thread (through the
export job).

Depsgraph: Use gset instead of unordreed_unordered_set

Depsgraph: Remove unordered map utility

Is not in use anymore.

Hopefully speed still stays at the same level.

Depsgraph: Use GHash for components in ID node

Fix for node group updates: need to force-update the group node because of crappy node update system.

Depsgraph: Use GHash for operation nodes stored in component

Fix node tree group relations.

Recent commits removed an important depsgraph relation between a node group and its tree.

Revert changes done to the transform matrix read/write and axis
conversion code to the state of the original patch.

The rewrite wasn't ideal, and prone to bugs. The idea was to not
hardcode Y-up <-> Z-up conversions but rather let the user choose the
axis during the export/import process, but since the other DCCs commonly
found in VFX pipeline all use a Y-up system, hardcoding everything
should be fine for the time being. This will probably be revisited in
the future if need be.

Depsgraph: Use GHash for the id map

Depsgraph: Remove use of std::hash, we have our own functions for that
