7539	JOSM autoupdate	akks	team	"People ask me often, why JOSM does not have auto-update feature.
Of course there are JavaWebStart and custom update-and-launch python/perl/bash scripts, but they are not suitable for novices. JWS works OK, but people are not used to it and its behavior can not be controlled from JOSM itself (and no portable version updating is possible).

I propose to introduce optional ""Firefox-like"" auto-updating: 
- When updating is on (or user press Update button or menu item), JOSM downloads replacement JAR if needed (latest->latest,  tested->tested) by DownloadFileTask.
- On next start separate launcher renames files on startup (maybe, keeping old versions) and launches newly downloaded version.
