Should display only one dialog when multiple conflicts exists

[naoliv]

While reverting a lot of changesets where multiple conflicts exists we can see something like this:

Since the dialog basically only has an "Accept" button, JOSM should group all the conflicts and only display a single dialog at the end, with something like "XXXXX conflicts detected in total"

I don't know if it's related with JOSM itself or with the reverter plugins (so I am leaving the component on Core).
