Attachment points

[i-make-robots]

Work on #235

1. Replace End Effector (Pose) with End Effector (Attachment Point)
2. Click isAttached to grab anything in reach.
3. Things in reach must be Pose items within radius of AttachmentPoint. They must also be immediate children of the Scene root.
4. The attached item will move from the Scene root and become a child of AttachmentPoint. On release all children of AttachmentPoint will be moved back to the Scene root. In both cases their relative positions will be adjusted so they do not teleport.

Also, Dials now show current angles when the panel is created.

Also, searching for nodes is now (by default) case insensitive. Use the Aa button to toggle case-sensitive search on.
