Spoike 4d9ee2395a warn clients when stuff will be invisible due to protocol limits. this does not include extra features, only limits. 
try to handle mvd prespawning a little more generically, to enable support for vweps (when protocol extensions are active). also fix issues with mid-demo map changes, which can potentially affect qtv streams.
