varying behaviour using Enter and Escape

[malenki]

At different dialogs in Josm Enter and Escape are handled differently.
For example in in the settings-dialog Escape cancels the dialog, Enter submits changes.

At the uploading-dialog hitting Enter and Escape results in nothing. One has to use tab and spacebar or the mouse to cancel or submit changes.

The same keys should everywhere cause the same reaction of the program.

Besides it would be useful if after editing the changeset-comment hitting enter would result in uploading => better workflow. Or should I file another ticket that for?
