Script to download and silent install Java Runtime

This script will download the small online installer, generate the silent install cfg file and run the installer.  The timer near the end is set for 3 minutes as it has to download the full installer first and Java takes a while to install anyway.  If you want to get the latest version just go to https://java.com/en/download/win10.jsp and copy the link from the button that says "Agree and start free download".  Then past this link into the $source variable.  I find that this installer works on both windows 7 and windows 10.
