[3dprinter-general] gbp wiki page

[Andrea Colangelo]

Here we go:

https://wiki.debian.org/3D-printer/gbp

So far, it contains just the bare minimum to start working with gbp,
and lacks some formatting to make the content more pleasant and easy
to read.

Next steps:
- gbp experts should check I didn't wrote something wrong.
- wiki syntax experts (I hate wiki syntax, my bad) may want to improve
formatting.
- gbp newbie can read the guide to tell me if something is obscure.
- add more content.

Ciao,
Andrea.
