Fixing a bug with placeholder api and other internal changes

Important Changes

1. The size of the plugin has been reduced considerably, so don't panic if you see it lighter, this is because the plugin is now exclusive to Paper.
2. Fixed a bug that PlaceholderAPI when returning values with legacy values the plugin was not converting its colors, now it processes them.
3. Change the methodology of use of PlaceholderAPI this no longer works as before and its keys %% now you have to use an internal tag to call PlaceholderAPI and the plugin can process the Placeholders, here are some examples.

PlaceholderAPI Examples

• Placeholder: %player_name% In MiniAnnouncer: <papi:player_name>
• Placeholder: %vault_prefix% In MiniAnnouncer: <papi:vault_prefix>
• Placeholder: %vault_eco_balance_formatted% In MiniAnnouncer: <papi:vault_eco_balance_formatted>
