- added new status image for illuminated underground - made Li'sar start at level 2 and be upgradeable to level 3 - made it so users in lobby can see minimap of non-shroud games being played - made it so the 'observer' setting is respected for multiplayer games - made it so that the number of available positions in a game is shown in the lobby - made it so the current turn of a game underway is shown in the lobby - made the 'eye of the observer' work, allowing players to see who is observing their game. (only updates when it's a network player's turn)
