Part 1 of a two-part revolution in Linux console graphics. Map all the line-drawing Unicode characters to similar glyphs. This means all our nice corners freely translate into rigid corners etc in the console, rather than hateful default characters (usually black diamonds). The demo and all widgets now look correct when drawing lines and boxes. Next, we'll add the actual glyphs for the block-drawing characters, and we'll have the finest graphics ever seen on a text-mode Linux console. #201
