tty/wintty.c w/o TEXTCOLOR

Browse Source 
With TEXTCOLOR disabled, compiler warnings about term_start_color()
and term_end_color() not being declared were followed by link failure
because they weren't available.

This tries to simplify color handling in the tty status code without
resorting to #if TEXTCOLOR (the proper fix, but somewhat intrusive).
For the usual case where TEXTCOLOR is defined, there were instances
of
  if (color != NO_COLOR && color != CLR_MAX)
    term_start_color();
  ...
  if (color != NO_COLOR)
    term_end_color();
and also of
  if (color != NO_COLOR)
    term_start_color();
  ...
  if (color != NO_COLOR)
    term_end_color();
I've changed both types to be
  if (color != NO_COLOR && color != CLR_MAX)
    term_start_color();
  ...
  if (color != NO_COLOR && color != CLR_MAX)
    term_end_color();
so that start/end pairing will always be consistent.

Also, ((color_and_attr & 0xFF00) >> 8) might not work as intended if
using 16-bit int and color_and_attr happened to have its sign bit set.
Change to ((color_and_attr >> 8) & 0x00FF) to ensure just the desired
bits.

Also also, a couple more formatting bits.
