Added functionality to watchdog aspect. Watchdog Annotation now have optional id and suppressThrowsExceptions attributes.
If suppressThrowsExceptions is set to true and an exception occurs, then all exceptions that can be cast to any of the "throws" exceptions of a methods will be ignored.

Use apache-commons-lang3 ReflectionToStringBuilder class for parameter and instance string representations. ( ==> evaluation if performance issues occur during creation of string representation)
