COMPAS Plotter 1.0.1-rc0

Added

• Created compas_plotter.__all_plugins__, so COMPAS's plugin manager discovers the
  register_scene_objects factory through the standard collect_all path (the
  same mechanism compas_viewer uses).

Changed

Removed

• Removed Eager, import-time register_scene_objects() call in
  compas_plotter.scene, and the from . import scene side-effect import in
  compas_plotter/__init__.py. These populated COMPAS's global
  ITEM_SCENEOBJECT at import time, which suppressed the lazy
  if not ITEM_SCENEOBJECT discovery trigger in compas.scene.context and left
  every other backend unregistered.
