Generate all JNLP at once

[steph-k]

We have dozens of applications on each of our servers. I'd like to have an option to generate all EXE at once for each JNLP application on that server.
It would also be fine, if I could call the JnlpExePacker to do this in batch so I can add it to our refresh routine, where we build all JNLP already for new applications, that got moved to the server.
This would save a lot of manual work, again and again
