do add (deleted) entities without geometry for popup info
handle special cases when old or new entity is out of scope
update underscore.js
omit unchanged entities ('modified' but no changes in scope)
workaround for equal start/end time in changesets (subtract on second)
workaround fix + always load relations for changeset
better relation styling
filter loaded data by changeset (query only by changeset time and bbox)
relations param for changeset, changeset param for url; fix url regex
use changed filter for changeset (faster)
remove unnecessary check (would require further check)
disabled out of scope detection for create, wrong for summarized changes
consider relations with only member roles changed
