Symmetrize Armature now also symmetrizes the transform of custom bone
shapes.

//Parameters//:

- **direction **(enum in ['NEGATIVE_X', 'POSITIVE_X'], (optional)) –
  **Direction**, Which sides to copy from and to (when both are selected)

- **custom_shape **(enum in ['SYMMETRIZE_SAME', 'SYMMETRIZE_ALL',
  'SYMMETRIZE_NONE'], (optional)) – **Custom Shapes**, Wether to
  symmetrize non symmetric custom bone shapes, all custom shapes, or
  none at all
