Subject: vim: highlight nbsp (\xa0) and force white fg on ExtraWhitespace

In addition to highlighting trailing whitespace it also highlights the
NBSP character (\xa0). This character is easily mistyped on MacOS.

As an extra improvement it force ExtraWhitespace foreground highlighting
to be white.
