Updated to EUnit version 2.2.0

  New macros assertNotMatch(Guard, Expr), assertNotEqual(Unexpected, Expr),
  and assertNotException(Class, Term, Expr).

  The debugMsg macro now also prints the pid of the current process.

  When testing all modules in a directory, tests in <Module>_tests.erl are
  no longer executed twice.

  The use of 'regexp' internally has been replaced with 're'.
