Hi guys,

I made many changes in AssetCategory and AssetVocabulary, but the last commits are only for AssetCategory, Could you please review my changes and apply the same for AssetVocabulary?

Also, Could you create some test for both class? You should extend the BaseSearchTestCase class and you have an example in DLFolderSearchTest to copy from.

Thanks!!
