Feat/view album fields

Implemented feature view a single albums fields: title, author, tags, description. Did a bit of refactoring in ImageAlbumService: moved tag-related methods to the new TagRepository.

Great job Eirik! There was little "logic" to this MR so i have few things to comment. Clever adding that Tag service!

My only thought is that I feel you could have moved a lot of the logic/tasks in viewalbum to a service instead. But then again I am not sure of what is the best practice in this case...
