Windows: colored terminal vs wx

[newville]

Weird but True:

Using colorama (or pyreadline) for colored ANSI text on Windows somehow interferes with (or hijacks/disables/supercedes) the wx input-hook that allows wx Widgets (like plotting) to be responsive and interactive from the command line.

This needs investigation, and may be non-trivial. For example, I think that IPython somehow manages to solve this (and uses pyreadline to get a replacement StdOutput.... hmmm).

For the time being, color output should be suppressed from the Windows command terminal, as interactive widgets are more important. It also emphasizes that the new support for color should be translated and supported in the wxLarch GUI (which is a reasonable alternate to the command line on Windows).
