Add lib/j_unit.rb to be able to omit the require 'yarjuf' statements

[bsingr]

Without this I had to do rspec -r yarjuf -f JUnit or bundle exec rspec -f JUnit to load yarjuf before rspec was loaded. Otherwiese (e.g. putting require 'yarjuf'in a spec_helper.rb) errors like this were raised:

After the change I made you can just do rspec -f JUnit without doing any pre-require statements.

@dpree Could you change the tests so they pass? At the moment they all fail...

[bsingr]

@natritmeyer sorry, wasn't aware of the ./features directory.

with my latest fix all tests pass (cucumber + rspec) at least for me. can u confirm?

[natritmeyer]

@dpree the tests are still requiring the yarjuf gem before rspec has loaded. See here for an example:

yarjuf/features/basic.feature

Line 17 in ad39fff

When I run `rspec spec/basic_spec.rb -r ../../lib/yarjuf -f JUnit`

As it stands, the tests are executing the following:
rspec spec/basic_spec.rb -r ../../lib/yarjuf -f JUnit

...but in order to test yarjuf without loading it before rspec (the purpose of your pull request - and an awesome change it would be!) the tests need to be executing the following:
rspec spec/basic_spec.rb -f JUnit

However, having tried the code in this pull request without "-r ../../lib/yarjuf" and also having added a spec_helper.rb file that contains require "yarjuf", I can't get the tests to work. What I get is this:

  Scenario: Requiring Yarjuf                       # features/basic.feature:24
    When I run `rspec spec/basic_spec.rb -f JUnit` # aruba-0.5.3/lib/aruba/cucumber.rb:60
    Then the exit status should be 0               # aruba-0.5.3/lib/aruba/cucumber.rb:154
      Exit status was 1 but expected it to be 0. Output:
