[Co-op] Voodoo dolls not supported
JDoom doesn't support Voodoo dolls in co-op at tall. They only appear in Single Player.
Vanilla Doom "supports" voodoo dolls in co-op for all present players; indeed, both TNT Map30 and Plutonia Map28 feature non-essential co-op Voodoo dolls.
This also affects JHeretic, but Dday has never supported Voodoo dolls in JHeretic at tall, not even in Single Player. I submitted an RFE about that ages ago: http://sourceforge.net/tracker/index.php?func=detail&aid=1955401&group_id=74815&atid=542102
As such, considering the MP code is to be rewritten for the upcoming 1.9 Beta7, maybe both these issues could be addressed.
