Title: Colorize hoogle output

Pass the --color option to hoogle, and apply the ansi escape sequences it generates in order to colorize the help buffer.

I'm not necessarily expecting that this can be merged as-is, since it assumes that
the user's "hoogle" has "--color" support, and I'm not sure if that assumption is reasonable.
