Inconsisten use of BroadcasterFactory in AtmosphereFramework

[pierreh]

In AtmosphereFramework.java a BroadcasterFactory is determined and created and set in the the field broadcasterFactory. However this field is not consistently used. For instance in doCometSupport :
req.setAttribute(BROADCASTER_FACTORY, BroadcasterFactory.getDefault());

Not sure if this is an issue because the BroadcasterFactory.factory is updated through the AtmosphereFramework. However perhaps it is best to keep a consistent location from where to access it.
