Hoogle: colorize hoogle cli output using haskell-mode font-lock

[jaor]

It's been a long time since hoogle command line interface lost the ability to
output ANSI colors (see ndmitchell/hoogle#133).

This patch makes haskell-hoogle to use emacs font lock to fontify its output,
with a custom flag to opt out.

This makes sense to me, but if it actually works then I'd suggest we do without the flag. Or does it not work so well? My rationale here is: the fewer knobs and switches, the better.

it's worked fine for my needs at least, the only reason for the flag was to not surprise previous users.

yes, i think (at least generally speaking) i agree with that.

Okay, I removed the defcustom and merged the changes — thanks!
