Clear cancelled resurrections announced over HealComm and CTRA

ParseChatMessage tested the raw message for "RessStop", which no
HealComm message is, so ParseComm's Resurrection/stop/ result was never
acted on. CTRA's RESNO was matched against the whole message, but it
carries the target's name, and the CTRA parser only recognised RES. A
cancelled rez from another player left the icon on the target's frame
until they were revived. RessStop still keeps a rez whose cast landed
and whose accept window is open.
