SQL support

[Muspah]

Draft to have some sort of to-do, follow-up, et cetera.

Known issues, to-fix:

• Top10 generating will not work (searches for island directory)
• slandInfo -> fix commented-out hasPerm
• Last island config
• Orphans
• Signs.yml?
• Fix island perm toggling
• MySQL/MariaDB/Postgres
• SQLite?
• File-based YAML including export-to-yaml, to be able to re-import into another DB schema
• Check this:
