fixed receiving one JSON object over multiple packets

js/rpcconn.js

 				obj = JSON.parse(json);
 			} catch (err) {
 				console.log("Failed to parse JSON: '"+json+"'");
-				throw err;
+				return;
 			}

 		//Digest JSON lines as they come, but only if they're a whole line
 		var currdata = "";
 		this.sock.on("data", d => {
-			var s = d.toString();
-			currdata += s;
-			var arr = s.split("\n");

-				onjson(arr.shift());

+			var start = 0;
