(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).
send string.char(0 to 7) to change colors
(red=0, orange, yellow, green, cyan, blue, purple, magenta=7)
the panel remembers the last color used (saved in the meta of the
left-most/"master" panel node)
