Improvements to BanPeer Code, mainly from a UdpStunner perspective.

Browse source 
* Added UdpStunner::dropStunPeer() code to remove bad peer from stun list.
 * added calls to UdpStunner::dropStunPeer for BanLists going to/from DHT.
 * added  DEBUG_BANLIST_CONDENSE to remove unnecessary debug.
 * Improved UdpStunner::status() print out of stunlist.
 * Added extra check to throw away stun reports where remote_addr == reported ext_addr.
	- This was causing peers to get the wrong IP addresses.
 * Modified UdpStunner ExtAddr checks to make sure the IP addresses match.
 * Changed BANLIST service Id to from Test ID to real ID.

NOTE: These are stop-gap methods to avoid the wrong Stun reports.
A more robust scheme must be implemented. I'd expect that it would
involve a strict initial check to establish your IP address...
(e.g. require 4 peers to confirm it, allowing for some fake entries)
After this we can have a weaker check ensuring IP address matches.
If we detect a likely REAL change of IP address - drop back to requiring
a strick check again.
