In-Window Reload/Refresh (or Trash)

I want to destroy the man sometimes, when I've made a mess out of him or the world.

All I can do is Ctrl + R.

Possible to add an in-window button to clear + reset scene without re-loading BVH file? A "clear world" button? Otherwise I'll note the importance of Refreshing in wiki.

Alternately: Deleting performers could be done in the bar.
