Added an ability to set log path and log level from external process e.g. Mirth Connect Deploy script.

var url = new Packages.java.io.File("conf//hpdconfig.xml").toURI().toURL();
var is = url.openStream();
var hpdClient = new Packages.com.mirth.mail.hpd.client.HPDClient(is);
hpdClient.InitLog("logs/hpd.log", Packages.java.util.logging.Level.ALL);
globalChannelMap.put("hpdClient", hpdClient);
return;
