Superheroes | Classes, Origins, Races

Switched over the main configs, language.yml, database.yml and config.yml to be loaded with Jackson rather than the old spigot built-in method. This should still be backwards compatibility, with the exception that defaultHero now needs an icon specifying (see the new default config). I've added a heroGainedSound property to all heroes, you can see an example in the new default zeus.yml as this was requested by someone in #plugin-help
