Migrate to a new data storage method

[flashgnash]

Given the modularization of the RPG systems, eventually more systems are going to be developed

The database schema is eventually going to become a massive pain to maintain with columns specific to each system

Currently, the way forward seems to be elastic search

Elastic search is a no sql data storage method, and allows for dynamic json blobs.

This means less strict schema validation, which means when different modules start needing different data points stored, they can just do so without needing to update the DB schema (meaning missing columns will needed to be handled gracefully and treated as empty values)

(this will also be needed if the bot goes public at some point, as sqlite will not stand up to a large number of users)
