Migration to Oracle Java 7 packager

# Usage of new Oracle's tool for making bundle

-- see https://java.net/downloads/appbundler/appbundler.html
-- not flexible as before but it does its work pretty well

# Oracle Java bugs
-- what Apple created, Oracle bugged - so we need to turn it off
-- new File("gateways") does not work correctly, getAbsoluteFile fixed it (yeah, I know - nasty way to fix it)
