v0.3.0

• Teams no longer have their own SQL table; you will need to DROP COLUMN associated_team on your matches tables if you use SQLite as a backend.
  • Many methods that work with teams have been removed; instead, manipulate matches.
• The JSON backend is no longer supported; it may work but should not be relied upon in production. SQLite is simple enough to install and set up that it should not present a barrier to usage
• As per the semver specification, "[the] major version zero (0.y.z) is for initial development ... [t]he public API SHOULD NOT be considered stable." Thus, this breaking change does not necessitate a v1 release.
• StorageBackend#getMatchByNumber has been removed.
