RLGWebD: shterm.js annotate

annotate shterm.js @ 163:0f6da35b27a0

RLGWebD: overhaul the list of current games. The /status WebSocket now only sends a complete list when opened. At 40-second intervals, it sends a list of games that have been updated in the last minute. The client now uses this to keep its own list.
