Adding a DocumentService to clean up the FileService, and get Documents well seperated, as it seems likely be pulled out or seperated in the future, there is now a Documents api file as well, for the same reason.
Some other minor changes are just fixing white space to assure our code is linting correctly.
I removed _create_study_workflow_approvals from the base test, as we don't use approvals like this anymore.
Record the size of a file in the database for quick access (this helps with a frontend refactor, so it isn't downloading the file just to see it's size)
Cleaning up the timing/performance metric reporting to make it easier to read.
Fixing a bug that prevented non-admins for getting the document-directory
Fixing workflow sync paths that were incorrect.
Repairing a suddenly failing test in files, that just don't make no sense.
Bumping spiffworkflow that contains a fix for issue #155
