Add an inactive friends list based on last seen Unix timestamp.
Add a method of removing a specific peer based on peer_id.
As fas as I know, the same pgp_id will discorvery themself and add online subnodes automaticlly even you remove one of them their just keep coming back, but if you accidently add your own peer_id on the WebUI, the peer list will show two identical PGP names and its subnodes, untill the retroshare gets restarted.
And this modification don't add the same peer_id as long as it belongs to your current node, it doesn't mean you can't add your new nodes with the same pgp_id but different peer_id.
Honor the Allman indent style
Now it is possible to trigger a connection attempt via JSON API
The API call success with any valid peer id
/peers/attempt_connection
{"peer_id":"d441e8890164a0f335ad75acc59b5a49"}
{"data":null,"debug_msg":"","returncode":"ok"}
The API call fail if the peer id is invalid
/peers/attempt_connection
{peer_id:"9090"}
{"data":null,"debug_msg":"Invalid peer_id\n","returncode":"fail"}
