Make runserver output colorful HTTP status codes

[Rob Hudson <treborhudson@…>]

While developing locally and using the built-in server, it is helpful to be able to quickly scan and see 404s, redirects, errors, etc. The attached diff adds 4 HTTP colors for each of the HTTP status codes of 2xx, 3xx, 4xx, and 5xx.

Add HTTP colors to runserver output

PS: This is similar to #1491. I'll also attach a screenshot of it in action.

The most recent patch is a good start; here are a few comments:

1) I'd rather see the whole line colorized - not just the status code.

2) 2XX is a normal success - I'd argue that shouldn't have any colorization. The 3XX case is worth noting (and worth being easy to see), but it probably doesn't need to be bold. The 4XX and 5XX cases are both bad, and should be bold, and in warning colors (yellow/red))

3) Blue is a really bad choice of color for 3XX - its almost invisible on a black background. Green would be a better choice

4) I'd rather see this display code isolated to the development server. By putting it in basehttp, every single Django server will be colorizing - even if that colorization is a no-op. This is an overhead that the dev server can wear, but we shouldn't force onto every WSGI/mod_python/fcgi.
