v0.7.0

Changelog

• Abilities. The privilege system has been completely replaced with a new activity-based abilities system. See the meta post about it for full details.
• Post types. The post types system has also been completely reworked; it's now much easier to define and use custom post types.
• Community resources: the post types upgrade opens the door for a post type that anyone with the unrestricted ability can edit without having to go through review - ideal for a community's shared resources.
• Table of contents: parent posts (such as questions) may now include a table of contents to quickly list their answers (which can also function as a leaderboard)
• System banners: a sysadmin can now set a system-wide banner to appear on every page visit, for user messaging.
