Support url as "path to eclipse java formatter config file"

[u3r]

In a multi-developer & multi-project environment it would be nice if the formatter could be placed online and synchronized/updated on-startup or once a day.

As a workaround you could put the configuration on a fileshare, which you have mounted into your filesystem. A cron job or another trigger could update the file once a day. Or put it in a GIT repo and a trigger clones the file once a day.
