change colors config, use 8bit color scheme instead of color name alias
switch to false severals configs vars
add ansi_colors function who init __ansi.colors using mongo_hacker_config.colors
Oops, ansi_colors return hash of list, not of strings
allows colorize func to read bright and underline from mongo_hacker_config.colors as default
add system color key in config.js
add security check in colorize: return string if color is not defined
