Timestamps in GC Logs for Windows services

As of Java 8, you can now enter the timestamp as a variable in a Windows service (%t), and it will resolve to the current time. That means we can finally have timestamps in gc logs for Windows services, which means they won't be overwritten on restart.

Add this as the gc log filename: gc-%t.log (to do this you will need to escape the % sign in the ant task with a double %%)
