Subject: [PATCH 1/2] AutoUV Segmenting was rewritten the AutoUV state

When a user opened multiple AutoUV Segmenting windows, each window kept its
state (#st{}) frozen at the moment it was created. After completing the
segmentation process in one window and activating the AutoUV Editor, if the
user switched to another segmenting window, the Geometry window would show
that the previously segmented object had lost its segmentation.

Note:
- Fixed an issue with multiple AutoUV Segmenting window erasing the
  previous segmentation. Thanks to Arclite.
