- Comments are stored in HTML as well as Markdown, so that conversion
only happens when saving (rather than when viewing).
- Added 'markdown' Jinja filter for easy development. This is quite
a heavy filter, so it shouldn't be used (much) in production.
- Added CLI command to update schemas on existing node types.
Refactor of pillar-server and pillar-web into a single python package. This
simplifies the overall architecture of pillar applications.
