v1.6.4: Add disable_cache option

This update adds a new option called disable_cache to the config.yml

When set to true (Defaults to false) will the caching of players be disabled. This means the following:

• No player names will be loaded from the cache.data file, if present
• No cache.data file will be created if none is present
• No player data will be saved to the cache.data file when the plugin gets disabled

Placeholders

It's important to note, that any placeholder requiring a cached player will NOT work when this option is used.

In particular, the following placeholders won't work:

• ${player name} (Will display the text set in unknown_player)
• ${player hasPlayedBefore}
• ${player isBanned}
• ${player isWhitelisted}
• ${player uuid}
• Any PlaceholderAPI placeholders
