Should be able to install multiple apps via command-line tool nwlink

[Tatone26]

Problem you'd like to fix

When programming apps for epsilon, just for fun, I use nwlink a lot. Very useful tool ! But when I'm finished, I would like to get back all my apps. The only way to do so is go to numworks.com/apps and select multiple .nwa files. I would love nwlink to be able to give multiple files to install, like the website. I know very few people will use that, but since the website can do it it should not be very difficult :)

Describe the solution you'd like

"nwlink install-nwa x.nwa y.nwa z.nwa" should install all three files. Right now, it installs only the first one.

Describe alternatives you've considered

Using the website works I guess, but it is a bit painful. I tried using the command multiple times, but it deletes all external data every time.
