+ decrease way references in osm_node_chain_free

+ cleaner selection handling with respect to invisible nodes
+ switch to goocanvas
+ use normal mercartor instead of utm
+ check bounds for placed/moved nodes
- scale (overlay?)
+ include ways, a node is part of, into relation check
o remove double first/last points from polygons (not worth the effort)
- avoid duplicate nodes in ways after node removal
+ prevent placing of things outside map
+ use first label in presets as dialog name
+ scale presets dialogs nicer
- join nodes (blue touchnode)
- make projects without osm file editable but not openable
- colorize on-the-fly

- Use JOSMs elemstyles.xml
- Handle relations
+ Use a real toolbar for the iconbar
+ keep wms layer after upload
- use systems proxy settings
- scroll by cursor keys/dpad
- "tag clash" resolve dialog used when joining nodes/ways
+ exclude ways with "new" nodes from upload. (e.g. upload failure)
- exclude nodes with existing ways from deletion (e.g. after way del failure)
+ retry on "internal server error" 500 
+ upload order: create/modify nodes, create/modify ways, del ways, del nodes
