Receive changeset parameters on the url

[willemarcel]

I was thinking about to add a resource to OSMCha heavy users that would load the RevertUi to revert the current OSMCha changeset. So we would need to modify the RevertUI to receive that parameter on the URL. What do you think about, @Zverik ?

I didn't know you used it :) My main concern is that it makes easier to abuse RevertUI, e.g. filling the entire queue for a week.

I think I can make it autofill the changeset list with the one passed in URL, but a user would still need to enter a comment and press a button.
