Create a simple web service to convert an FTN nodelist to syncterm.lst

Tested with this:
wget --content-disposition --post-file=nodelist.010 http://synchro.net/fido-nodelist-syncterm.ssjs

web/root/fido-nodelist-syncterm.ssjs

+var nodelist = new File(system.temp_dir + "nodelist.txt");
+if(!nodelist.open("w")) {
+	write("Error " + nodelist.error + " opening " + nodelist.name);
+	exit(1);
+}
+nodelist.write(http_request.post_data, http_request.post_data.length);
+nodelist.close();
+
+var syncterm = new File(system.temp_dir + "syncterm.lst");
+
+load({}, "fido-nodelist-syncterm.js", nodelist.name, syncterm.name);
+if(!syncterm.open("r")) {
+	write("Error " + syncterm.error + " opening " + syncterm.name);
+	exit(2);
+}
+
+http_reply.header["Content-Type"] = "application/octet-stream";
+http_reply.header["Content-Disposition"] = 'inline; filename="syncterm.lst"';
+http_reply.status = "200 here's your file";
+writeln(syncterm.read());
