No "t." for the migration DSL!

Now you can omit |t| block parameter and all the t. from your migration code, that means, the syntax looks more Rails-3-ish, like the routes DSL and ActionMailer DSL.
Also, this change won't break any of your existing migration files, since the traditional syntax is still available.
