Improved matchers and opening log file

1. If there were failures during tests, after all tests DUnit will offer to open saved log file to review failures in details.
2. Improved matchers with:
   • proper constructor agruments naming
   • new method in IMatcher - GetExpectedAndActualAsString which should be implemented to show difference between expected and actual.
   • new matcher - ArraySimpleValueMatcher which compares arrays with simple values inside
   • static constractors for SimpleValueMatcher and ArraySimpleValueMatcher. To use call MatcherFactory.SimpleValue or MatcherFactory.ArraySimpleValue
