Changes

tsk14 EJB search story by text
Adds function to search for a story by text, formats the dataset date to
a timestamp to match the one in the xml. Adds test to EJB.

tsk14 TestStoryEJB corrected
Fixes test in storyEJB, the test to search stories by title or content
fails, it happens by using is instead of
IsEqualToStory.containsStoriesInAnyOrder(), also changed to
Matchers.hasSize() to evaluate the size of the lists.
