Step class cleanup

[gapipro]

Right now when step is triggered attached element gets all "shepherd-*" classes but when step is closed this classes should be cleaned up.

Any particular reason this is not happening?

👍 I agree, this functionality would be great to have.

I assumed everything was left in place for quicker setup of the tour again, if you wanted to trigger it a second time. However, it would be nice to have it cleaned up.

I believe all this is cleaned up now 👍
