Merge pull request #18 from oodgaard/dateset

Updated the Model\Vo\Date::set() method to correctly set the date.
Restructure tests to be in own VO namespace. Use UTC as the default timezone otherwise tests will fail for people in different timezones. Reuse code.
Strict comparison, namespace resolution and fixing of the timezone in the tests.
