basic support for the ISO-8859-1 character set

Browse Source 
(sorry, no UTF-8 here, Lue doesn't do multi-byte too well in this situation)
plus a bunch of symbols stuffed into the empty 128-159 range that should be
useful on a marquee:

128,129: musical notes
130-140: box drawing glyphs
141-144: block shades
145-152: arrows
153-156: explosion/splat
157-159: smileys

This commit changes the "all on" keyword to point to char(144), and
"cursor" is moved to char(31).
