Reaccji-Spelling

[shawnrc]

This'd be an extension of the existing Slack Action functionality - folks should be able to expand the dropdown for a given message and select a React action. From there, they should see a Message Menu and a list of pre-determined reaction messages to select from. After selecting a message, Kemohno should emoji-spell it and react using the generated collection.

The problem is that a given reacji message can't have too many duplicate letters - if you exhaust an instance's supply of Ys, you can't spell past that point if the message has more Ys in it. Slack only allows an emoji to be reacted with once.

A reacji message should be representable by an ordered set. This makes spelling normally less than optimal since it's possible to get into a state where you're constantly re-rolling to get a non-duplicate emoji. It also makes the compute time of a given message non-deterministic, which is also less than great.

Pre-defining reaction spells will make reactions predictable, but it's unlikely that folks will care that much.
