No link/reference to refmt tool

[juszczakn]

This might not be the correct spot for this, but I've been trying to find what/where this refmt tool actually is located for about an hour now, and have had no luck. There are broken links on the reasonml site itself for previous versions it seems, however I can't find any solid reference to it anymore.

It seems to me that it would be very helpful to just link to the home site for refmt in the README, or if it's abandonware, remove references/code related to it.
