-Hunt overview commands and filters
-----------------------------------
-
-• Implement a /hunt command for giving an overview of the entire hunt,
- (like the Turbot "home" view but available in any channel)
-
-• For "/hunt" display only unsolved puzzles by default, but also allow
- for "/hunt all" to display all puzzles
-
-• On the Turbot home screen allow a dropdown for Unsolved/Solved/All
- puzzles
+• Fix slash commands to pass off processing to a separate Lambda and
+ then return immediately (removing the annoying "operation timeout"
+ complaints from Slack even when the command works exactly as it
+ should).
