Duplicate peers

[Mark Nottingham]

Because peerGetSomeParent and then peerGetAllParents are both called  
in the NEVER_DIRECT case (e.g., accelerators), the list of peers to  
use will contain a duplicate; whatever peerGetSomeParent returns will  
be in the list twice, and if it's the first peer (lexically in the  
conf file), it'll be twice in a row. This isn't good, especially for  
round-robin accelerator setups.
Attached patch skips duplicates of the first peer list entry (in the  
long term, this might need to be reworked, but this seems like a low- 
cost way to improve things for the time being).
