improve normalization of DTOs so serializing them works more reliably, and add a couple of other bugfixes related to managing the current workspace, view, etc. during resolve / render operations.
use master branch of galley now that the jxpath stuff is merged, and forcibly add the view roots to the references collection for a web before passing it back. This last bit is to deal with repository builds and the like that reference a BOM as a root, but don't want managed relationships returned.
