ANN: LC Documentation Cache Cleaner

[Bob Sneidar]

Handy, but it didn't quite work correctly. I selected all but the 9.0.1 rc1, and tried to uncheck confirm, but it confirmed anyway, and deleted everything but the first 8. I had to do multiple passes before I got them all. 

Clicking the confirmation checkbox did not unhilite the button, but rather showed and hid a green checkmark icon.
