Updated font and fs lib; updated editor; updated sf2dlib

Browse source 
Libs additions: font.load, font:unload, font:getWidth, fs.getDirectory, fs.setDirectory, fs.exists

Editor additions: syntaxic coloring and mono font

sf2dlib update: you will need the latest version of ctrulib.

Also, because of the lib font needs, the sftdlib was modified.
