Commited the latest code in branch

Merge branch 'feature/blender_tangentanimrelease_cmake' into develop

The code that allows CLion to index the external library headers is only for Windows and CLion for now.

Add blender_tangentanimrelease.cmake config file for builds

To use the configuration on Windows the command line is like this:
cmake -G "Visual Studio 15 2017 Win64" -C "..blenderbuild_filescmakeconfigblender_tangentanimrelease.cmake" ..blender

To build it:
cmake --build . --target install --config RelWithDebInfo -- /maxcpucount

Rename yup_to_zup_attr_ to attrs_require_coord_convert_

A better name for the field "Y-Up to Z-Up Custom Attributes:" is "Require coordinate conversion:" That's in case there a forward and up axis fields are introduced as options in the future and so hard hard-coding the Y-Up to Z-Up conversion may eventually be removed in favour of options specifying the axes.

Handle Y-Up to Z-Up attribute string in MOD_meshsequencecache

1. Handle the yup_to_zup_attrs_str parameter in the MeshSequenceCache modifier.

2. This fixes an issue where animation wasn't applied, as a consequence to the previous change when the yup_to_zup_attrs_vec was introduced, since the yup_to_zup_attrs_str data wasn't being applied by applyModifier().

3. Make the appropriate RNA_def_property() calls for "import_attrs", and "yup_to_zup_attrs_str". Also add them to DNA_cachefile_types.h

4. Set maximum length of the yup_to_zup_attrs_str to 1024. 2048 is a little excessive.

5. Disable Ui for yup_to_zup_attrs_str when import_attrs is not enabled.

Add yup_to_zup_attrs option to Alembic Import, Fix errors in write_data_to_customdata, Alembic Import default options changed

1. Added "Y-up to Z-Up Custom Attributes" option which lets the user define which V3 (i.e. Vector 3) attributes should be converted from Y-Up coordinates to Z-Up coordinates.

2. Fix errors in abc_customdata.cc, write_data_to_customdata() that assumed config.user_data was a DerivedMesh * instead of a Mesh * pointer.

3. Changed Alembic Import options:
"set_frame_range" defaults to false now. "import_attrs" defaults to true now.

OpenVDB: Applied `make format` to apply the correct code style.

Fix crash when loading Alembic, cherry-picked from Tangent Anim blender278 remote

When initiating an Alembic import job, a scene update is set to run during the job, possibly causing data conflicts with the Alembic import thread.

This change makes the scene update run only after the import job is finished
