Fixes #217. Add methods to the AD util class to convert to and from AD timestamps. Refactor existing methods in AD class to use these.

- rename getActualValue to getCurrentValue
- remove needless use of JNDI Attributes
- add some Javadoc

Restablish deprecated method getAttributeValueById (removed in r744). Log a warning regarding future removal.

Fixing build: String.isEmpty() is not available in Java 1.5. Maybe we should migrate to 1.6, but fixing for now anyway.

StackTrace should only be displayed on DEBUG

Remove unnecessarily thrown Exceptions

There is no need to catch Exceptions in tests, if a test throws an exception the test fails
If you want to test for an Exception use the expected field on the @Test annotation

Tests also should be as small as possible, it is best to avoid multiple asserts in one test
