Adapted mitkVectorTest

* fixed calls to Equal for vnl_vector_fixed type
* changed the value used for the vnl_vector_fixed type, it caused
  precision problems toghether with the float type
* enhanced testing of vec2 != vec1 by testing vec2 == vec1 for higher
  epsilon tolerance
* replaced CONDITION_REQUIRED by simple CONDITION
