v0.8.0

It's been a while since our last release, so while there's not a single thing driving this timing, it felt right to make a new full version. Improvements include:

• Threaded comments
• Reactions such as "worked for me" and "outdated" (configurable)
• New search options
• Support for creating new post types
• Summary of votes received on the user profile page
• New configuration options and user preferences

Along with a lot of smaller fixes and improvements.
