New Glk implementation nanoglk, based on SDL

Hi!

Nanoglk version 0.0.1 has just appeared in the IF archive (directory if-archive/programming/glk/implementations). Nanoglk is a Glk implementation mainly focussed on portable devices with small screens, especially the Ben Nanonote, where it works already quite well (I’ve already played several games on it). I hope that SDL makes it easy to port on other platforms.

Notice that this is a very early version targetet at interested developers.
