19257	reduce number of ShowHistoryAction implementations	GerdP	GerdP	"follow up of #19254
We have multiple implementations of a class `ShowHistoryAction`
`org.openstreetmap.josm.gui.dialogs.changeset.ChangesetContentPanel.ShowHistoryAction`
`org.openstreetmap.josm.gui.dialogs.SelectionListDialog.ShowHistoryAction`
`org.openstreetmap.josm.gui.history.ShowHistoryAction`
They look very similar. We should have one implementation which can handle a collection of ids.
There is also `org.openstreetmap.josm.actions.HistoryInfoAction` which reacts on Ctrl+H.
At least they should all use `HistoryBrowserDialogManager` to do the real work of downloading data.
