Control Strict Pointer Mode from the CLI, defaulting to OFF

Due to issues with library overrides and unsynced pointers, it's quite
common for the Blender Animation Studio to get crashes of BAT. To avoid
these, Strict Pointer Mode is disabled when using BAT from the CLI.

Blender Cloud add-on will also get a similar update, so that there also
the Strict Pointer Mode is disabled.
