Summary:
Hi!

I'd like to be able in Interface Builder (Storyboard) or Xib) to take an existing UISlider and demote it to a UIView without having to delete and recreate.

My use case - I have an existing UISlider in a complex configuration (constraints, etc), and I want to replace it with a MPVolumeView. To do that, I have to add the MPVolumeView to a plain old view.   Right now, attempting to change the class of the slider to UIView is being rejected, requiring a lot of surgery to the interface.

Steps to Reproduce:
1. drag a UISlider into a view
2. select slider
3. Go to the command-option-3 panel
4. Type UIView in the "Class" textfield and press return

Expected Results:
5. Class changes to UIView, existing constraints are preserved. Things like UIControl connections get purged

Observed Results:
5. class textfield is cleared, and retains "UISlider" as the prompt text.
