Command registration

[pfist]

I'm still deciding how to approach this. Should Hiei handle command registration or leave it for the bot to deal with?

I would like to explore the possibility of automating command registration. Essentially: if local commands are different from remote commands, register commands again to keep them updated.

Tasks

• Move sortBy function to a new HieiUtil utility class
• Cleaner comparison
• Better variable names

I submitted a WIP slash command handler tonight with a first pass and command registry sync. So far it's looking doable. I'm able to compare local commands vs. remote commands, but the arrays aren't sorted identically. Remote commands are in a different order, so I need to figure that out. Maybe sort both arrays alphabetically before comparing?
