Added btf-eliminate, which makes it so that the element is eliminated if it is dropped outside of a dragon.
Renamed btf-eliminate to btf-dragon-eliminate to be consistent. Added btf-dragon-delay which defaults to zero, but when it's not zero it requires that amount of time to be waited before the element is picked up. This was added because I wanted to make the element clickable.
Removed btf-dragon-delay, elements are now clickable by default. When an element is dragged it is picked up.
Removed delay comment.
