The Rails application that powers OpenStreetMap

ChangesetController#update

updates a changeset's tags. none of the changeset's attributes are
user-modifiable, so they will be ignored.

changesets are not (yet?) versioned, so we don't have to deal with
history tables here. changesets are locked to a single user, however.

after succesful update, returns the XML of the changeset.
