Currently the UI for Symmetrize is confusing, for a few reasons:
- It exists as a sub-panel to the Dyntopo panel, even though it doesn't require Dyntopo to work
- It is inside a panel called Remesh, which is confusing because we now have a different Remesh panel
Changes:
- Put the Symmetrize controls in the Symmetry panel
- Rename Optimize to Rebuild BVH and move to the Sculpt menu
- Change the poll function - apparently it doesn't require Dyntopo
