drbob 4cd7523947 Incremental Improvements to DHT:
Added Knowledge of Friends, Friends of Friends and Relays.
	- Added bdfriendlist class to store information.
	- New interface function updateKnownPeer().
	- includes IP addresses, if known. (for filtering)

Bad Peer Filtering.
	- Check IDs against known peer IP addresses.
	- Added checks in checkPotentialPeer().
	- Added checks in addPeer().
	- Running in TestMode at the moment (Bad Peers are only flagged).

Other Fixes:
	- Removed some warning about int/uint comparisons.
	- added bdSpace::flagpeer() fn to support above.
