If someone want to work on this, what needs to be done is to add support 
for the ESC;38;5;COLORNUMBERm ESC;$8;5;COLORNUMBERm escape sequences for setting the \
color background and foreground.

The colors 16 ... 256 can be computed with code like this:

for (r=g=b=0, i=16; i< 256; i++) {
   if (i < 232) {
	int j = i - 16;
	int r = j / 36, g = (j / 6) % 6, b = j % 6;
	int red =   (r == 0) ? 0 : r * 40 + 55;
	int green = (g == 0) ? 0 : g * 40 + 55;
	int blue =  (b == 0) ? 0 : b * 40 + 55;
	color.red   = red | red << 8  ;
	color.green = green | green << 8;
	color.blue  = blue | blue << 8;
    } else if (i < 256) {
	int shade = 8 + (i - 232) * 10;
	color.red = color.green = color.blue = shade | shade << 8;
   }

The colors 0 ... 16 are in TEWidget.cpp:base_color_table 2...9 and 12...19
