Original commit message from CVS: Landed the new improved capsnegotiation system. The main idea is to keep track of the possible data types that can pass through a connection. plugins can at any time inspect, adjust and refine these caps. plugins also get notified when something changes to the types so that they can reconfigure themselves. Look at the updated plugins and the soon to be finished doc.
