Comment 4 for bug 590528

Since Nicolai seems to be not active at the moment I tackled this bug. The load replay window is now very much like the load game window: you can see the same information and delete replays. If more information is wanted please add it to bug #846409, because this means a major change in the way how games are saved and loaded.
I also added some keyboard shortcuts to load replay and load game screens:
* up/down to navigate through the list
* del to delete
* enter to load / confirm deletion
* esc to go back / abort deletion

Fixed in revision 6039.
