Include Linux launcher

[Miss-Inputs]

I can't drag stuff onto the .exe even though Mono exists, so that kinda bugs me, and I guess that's just Thunar's fault, but still.

It would also mean I could have ROMniscience available as an "open with" option and other integrationy things, I guess. Probably?

If it's a shell script I could also put it in /usr/local/bin.

It's just more convenient at the moment.

I'm tired.
