Test::Unit support for Spork with ruby 1.9.x/2.0 and Rails 3/4 support

This includes a plugin for spork to enable Test::Unit support for spork. It also comes with a very bare-bones drb client to run tests.

Information about spork gem, how to install it and run is here https://github.com/sporkrb/spork

Then, once spork is running, invoke testdrb:

$ testdrb path/to/your_test.rb

to run your tests under Spork.

Good part is that you still able to run your tests in old manner, like

$ rake test TEST=path/to/your_test.rb

or simply

$ rake test

to tun all test suite.

Gotchas

This gem autoloads test_helper.rb file, so there is no need to require it in every test file. But if you have already a bunch of tests WITH require 'test_helper.rb' at the bottom of each test file and you need to be compatible with some CI servers (you don't want to remove that line) then to avoid error message like "no such file to load test_helper.rb" you will need to add these extra config line to Spork.prefork block:

Spork.prefork do
  $LOAD_PATH << "test/"
end

Now you should be compatible with Spork and CI servers.
