Use Web Sockets rather than long polling for Comet Actors and other stuff (delayed rendering, browser/server actors, etc.) if Web Sockets are available.

I guess also some sort of config to toggle this would be nice, even if WS would be available? I'm just thinking of the situations I've had with envs that have "something weird" with WS, even though they claimed to support it.

I think it's reasonable that, at least for a time, there's the ability to revert to long poll mode. @dpp Do you have any objections there?
