Updates: Towny Check, New Placeholders & Click Settings

Several useful improvements have been added to enhance both gameplay and server management:

️ Towny Region Check
A check for Towny towns has been added — teleportation is now blocked into Towny towns to prevent abuse and maintain fair play.

New Placeholder: %spacepvp_total_games%
Displays the total number of games played on the server. Great for stats pages, scoreboards, and leaderboards.

⚔️ New Placeholder: %spacepvp_kd_ratio%
Added PlaceholderAPI support for %spacepvp_kd_ratio%, which shows the player's Kill/Death ratio.

️ Configurable Click Types
You can now configure which click types (left-click, right-click, shift-click, etc.) will open the inventory preview. This allows more flexibility in customizing user interaction.

‍ New Placeholder: {player_displayname}
A new {player_displayname} placeholder is now available. It works just like {player_name}, but supports nicknames with colors and formatting.
If your server uses colored nicknames, consider replacing {player_name} with {player_displayname} for better display.

Additionally, {player} was replaced with {player_name} in the following messages for consistency:

• points_given
  
  
• points_take_insufficient
  
  
• points_check
  
  
• points_taken
