+ Turn off verbosity in Rakefile by default. Use `rake V=1` to turn back on.
+ MiniTest -> Minitest everywhere.
+ MiniTest::Unit::TestCase -> Minitest::Test everywhere.
+ Updated minitest doco urls to official and up-to-date site.
+ Normalize requires. Only needs "minitest/autorun" and "minitest/pride".
