With last version of Fitnesse, Fitnesse plugin waits for Fitnesse server start indefinitely.
This plugin looks at standard output to know if Fitnesse server is started.
Last version of Fitnesse doesn't write on stdout when the server start.
(since unclebob/fitnesse@91e93be - commit date: 13 nov 2013 - impacted version 20140201 & 20140418)
I have changed the code of Fitnesse for backward compatibility, but no release version yet.
