Field views should indicate when a player has lost

[xale]

Field views currently have no indication (except perhaps a "death field" update sent by the server, like Jetrix's "Jetrix field") that the player in that slot is dead, which makes it difficult to determine if a player is still playing.

Implementation note: the sexiest way to do this would probably be to "dim" the field, perhaps by applying a filter.

The game now automatically gives the local player a randomly-filled field when he or she loses, (which may be replaced by the server's "death field") but a filter or something over the field would still be cool to add later.
