6141	extend confict message on upload and provide a button to update. (WAS: warn before upload old/outdated data)	skyper	team	"Hi

Thanks for your work

It would be nice if JOSM displays a warning if you try to upload old or outdated data and give an advice/link to update the data first.

This is very useful if an upload fails and if you open an old file for example.

Thanks skyper
