Improvements to tango themes, including some faces from Jan Moringen.

* themes/tango-theme.el, themes/tango-dark-theme.el: Let-bind
tango palette colors.  Only define faces for color displays.
Customize the ansi-color-names-vector variable.  Add Ediff,
Flyspell, and Semantic faces as suggested by Jan Moringen.
