"Fields"-Option for single Document-request as well

[empesive]

And here is another Idea:
The powerful _find-Request does have the option "fields" were its possible to determine which fields of the matched documents should be returned. This optional "fields"-Option is missing on the GET DATABASE/DOCUMENT_ID - Request. When you using this request you get the whole document back, but is some cases it is neat to get only some on the document-fields back because only these might are interesting at the moment. Currently it is possible to do a workaround with the _find-Request so this feature is not that critical, but it would be nice when it will come someday so a workaround is unnecessary.
