2.0.0

Update to support latest Narrative.

• removed job info from Narratives list - no longer stored in Narrative and don't have time now to refactor
• Improved counting of sharing to make consistent across all narrative strips - count current user in sharing and improve the mouseover to clarify this
• Restore markdown and code cell counts in narrative cards
• Improve mouseover messages for apps, esp. when obsolete

Also, update to use the Narrative-friendly forms of kb_common and kb_service, which are now supported in kbase-ui
