quick hack to add experimental Overpass attic diff
trailing commas
used nodes
normalize input field styling
update base URL
loading panel (spinner + cancel)
live button (and status bar) disabled for now: not sure if actually used,
should probably be in a separate app/UI once refactoring is done
'now' as placeholder in max date field
remember osm_base timestamp as last visit
fix adding nodes without coordinates when no extent given (redundant?)
fix 'this' context for file drag&drop
option to load relations
formatting: replace tabs with spaces
update url
help and tooltips
experimental changeset loading (incomplete)
attic version
do add (deleted) entities without geometry for popup info
handle special cases when old or new entity is out of scope
