Add getWorkflowForDocument and getWorkflowStateForDocument, which do

what they say they do. Add getTransitionsForDocumentUser stub, which should eventually list the transitions available for a document (taking its current state into account) for a specific user (taking groups/roles into account). git-svn-id: https://kt-dms.svn.sourceforge.net/svnroot/kt-dms/trunk@3823 c91229c3-7414-0410-bfa2-8a42b809f60b
