Subject: [PATCH] Fix channel chat not showing new messages
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two bugs:
1. refreshMessages() compared array length to detect changes — at the
   200 message limit, new messages don't change the count. Now compares
   last message timestamp instead.
2. WS handler only triggered on type 'message' — observer-decoded
   GRP_TXT packets broadcast as type 'packet' were missed. Now also
   triggers refresh on packet events with GRP_TXT payload type.
