Remove shim from memory if GUI is detected

First good work on #4

In details it sounds like you just hid the process and I can tell that from procexp. Can you just terminate the process?

It's unfortunately the only way to do it. I tried various other hacks that didn't involve just hiding the window automatically but none worked.

An executable either acts:

• as a console app, in which case it must create a console window if opened via Win+R for instance, or
• as a Windows app, in which case it cannot interact with the console through stdout, stderr or stdin.

Since most scoop apps are command line utilities (at least in my case), the second solution wasn't doable. We could have two different .exes, but that would require scoop to track whether a shim points to a command line app or a Windows app.
