Overview

UUID Type First run at this, because I need it. A few caveats:

* Only works on postgres, using the built-in native uuid type.
  To make it work in mysql, you'll have to add a typemap entry to
  the mysql_adapter. I think. I don't have mysql handy, so I'm
  not going to try. For SQLite, this will have to inherit from the
  String primitive
* Won't accept a random default, because of the namespace clash
  between this and the UUIDtools gem. Also can't set the default
  type to UUID() (postgres-contrib's native generator) and
  automigrate, because auto_migrate! tries to make it a string "UUID()"

Feel free to enchance this, and delete these caveats when they’re fixed.
