Primarily optimizations around trying to fix the occasional database lock errors that have occasionally popped up in the past. I switched the database's journal mode to something which should support greater concurrency, and did a number of optimizations around using more indexes in different queries and move to bulk operations when possible. All saved messages in the game (journals, messengers, board posts, etc) had the method used to categorize them change, so please let me know if any don't show up where they should or vice-versa.
