Allow running of single test file

The default rails testing rake tasks support running just a single test:

    rake test TEST=test/controllers/widgets_controller_test.rb

But when using minitest-rails, the one test is run multiple times.
This change allows using the TEST env var and will only run that file once.
Version bump for 0.5.2 release
Hide single rake task

*sigh*

Ugh...

*shakes head*
Add deprecation warnings

Warn the users that these things are going to be removed in 1.0.
Rename test helper

Switch back to the default test helper name, for easier integration in Rails 4.
Update Rails 4 Gemfile

Use the beta1 gem now that it is released.
! Use newly added MiniTest::Spec::DSL

New direction for minitest-rails.
Instead of managing the ancestry to AS::TC, extend it with MT::S::DSL instead.
Allows for most of the complexity of minitest-rails to go away,
and we can focus on more on smoothing edges than maintaining hacks.
Thanks @zenspider!
