mod_bosh,mod_websocket: Make into global-shared modules (...again) Global modules aren't quite considered loaded onto hosts, which causes confusion in some cases. They are also reported in the log as being served on http://*:5280/foo which is also a bit confusing, and can't be clicked. Global modules also have to have their paths configured in the global section, which could be confusing and unexpected. This global+shared method should be the best of both worlds.
