91f70d2a4a
Added basic support for server sync. Re-added a few missing defers. Renamed TO-DO to TODO across the entire codebase. Renamed StaticForumStore to MemoryForumStore. The ForumStore is now built on a sync.Map with a view slice for generating /forums rather than a slice. Renamed many more functions and variables to satisfy the linter. increase_post_user_stats() and decrease_post_user_stats() are now methods on the User struct. We also fix a bug where they take the moderator's score rather than the target user's into account when recalculating their level after a post / topic is deleted. Transitioned the topic list to CSS Grid for Tempra Simple, with a float fallback. Cosmo and Cosmo Conflux are now hidden from the theme list. Fixed more data races. Added more debug data to the template compiler logs.
