converting attribute-text to html

4.29: adde/gui/converting attribute-text to html:
. a pyqt text object uses a system of fragments to express
each change in the text's combinations of attributes in
(color, bold shade, underline, italics, superscript, subscript );
but when converting to html,
you want to combine contiguous modes;
eg, say you have 3 words, 1,2,3,
with u=underline, and b=bold;
so, when pyqt gives you:
1(u), 2(b,u), 3(u)
your html writer should be converting that to:
u(1, b(2), 3) .
