Patch from David Lloyd <dmlloyd@tds.net>.  Removed the NO_BRIGHTCOLOR
and NO_BOLDOVERSTRIKE defines.  If you want to do NO_BRIGHTCOLOR, set
colors 8-16 the same as 0-7. :P  For bold overstrike, it's now an
option (--overstrike-bold).  There are also options to deactivate the
"bold" and "blink" attributes' setting of high-intensity colors, and
to allow non-default foreground colors to be bolded.

If true (default), Eterm will simulate a bold font by printing each
