Made the "I'm not going to delete this" message more clear
I was a bit confused and I assume others would be too. It makes sense, if you don't have a .virtphp file then its scared it might be some other directory and doesn't delete it. This relates to #52 I guess, as if its not made properly then it can't be deleted. Kinda a tricky situation.
