Color on info level

[csalazar]

Hi @untitaker , I see that info output is not colorful, there's some reason for that? Maybe I can do a PR to add support?

Thanks!

@csalazar Just run:

import logging;
import click_log;

[...]
click_log.ColorFormatter.colors['info'] = dict(fg="green")

This way all info tags should be green.

Also had this issue. This might be a good thing to add to documentation? How to customize colors? Or perhaps it might make more sense to add an optional parameter to the click_log constructor for colors?
