/**
 * Singleton class which deals with everything related to wizardry's config file. To access individual settings, use
 * {@link Wizardry#settings}. Also stores a few string constants for easy access.
 * <p></p>
 * As part of the 2.1 update and code overhaul, the way the config settings work in multiplayer has been tightened up.
 * Importantly, there are <b>three</b> different types of config options:
 * <p></p>
 * <li>Server-only settings. These only affect server-side code and hence are not synced. Changing these locally only
 * has an effect if the local game is the host, i.e. a dedicated server, a LAN host or a singleplayer world. Examples
 * include worldgen, mob drops and commands.
 * <li>Synchronised settings. These settings affect both client-side AND server-side code, and are synchronised with
 * each client on login via {@link Settings#sync(EntityPlayerMP)}. Changing these locally only has an effect if the
 * local game is the host, i.e. a dedicated server, a LAN host or a singleplayer world. Examples include discovery mode
 * and crafting recipes. <i> Note that as far as users are concerned, there is no difference in behaviour between
 * server-only and synchronised settings.</i>
 * <li>Client-only settings. These settings only affect client-side code and hence are not synced. Each client obeys its
 * own values for these, and changing them on a dedicated server will have no effect. These are usually only display and
 * controls settings.</li>
 * <p></p>
 * Each of the settings fields in this class is marked with one of the above categories to indicate which it belongs to.
 * This in turn dictates which logical side it should be called from: client, server or both. <b> Do not access a config
 * setting from the wrong side, because it may cause unexpected or strange behaviour.</b>
 * 
 * @since Wizardry 1.2
