Use the VT100 assets from my shellinabox fork

The shellinabox project is under GPL-2, so as far as I understand (who
actually went through the GPL and understood it all) every code changes
to the core files make your project a derivative work. A derivative work
should be licenced in the same terms as GPL-2.

I don't want that. I would like to stay as far from the GPL I can, so I
created my own fork, which is a derivative work. I make all of my fixes
in there, and here as I just use the code from it as is.
