Fix locale bug and parkour spawn position

- Fix locale 'true' bug with sanitization at all levels:
  * ConfigAccessor.getString() - force String.valueOf()
  * Option.java - sanitize LANG defaults from config
  * PlayerSettingsManager - sanitize on settings load
  * SQLDataMapper - sanitize on SQL load
  * StorageDisk - sanitize on JSON load
  * SQLMigrationManager - SQL migration to fix DB

- Fix parkour first block position:
  * Island.java - spawn 6 blocks forward + 1 up from center
  * GeneratorCleanup.java - same position after fall/reset

- Add spawn-location config option at top of config.yml
