Sharing Thoughts
updated logic to check if patient user can see shared thought link (must be member of unit with unit.sharedThoughtEnabled), responders not added by default to shared thought (user.sharedThoughtAdministrator must add user.sharedThoughtResponder in admin interface), only user.sharedThoughtAdministrator can add/remove responders (hidden buttons for add/remove).

conversation.messages set to Set (not List) to avoid occasionally causing bug in hibernate where it retrieves multiple copies of the same message

don't show ConversationType.SHARED_THOUGHT in conversation list

pagination missing datatables fix where messages.js is called

show time in Updated column in admin list of shared thought
