0.65 for 1.13/1.14/1.15

• Altered behaviour:
  • Previously using the channel command for the channel you're already speaking in would move you to the next default channel,
    or if non was found, the next global channel.
  • Ex: While being in townchat you use "/tc" you could find yourself in globalchat.
  • Now you will be told you're already in the channel you just used the command to enter into.
• Fixed: GLOBAL channelTypes (default: general and local channels) are no longer formatted by TownyChat if modify_chat.enabled is false.
  • DEFAULT, TOWN, NATION & ALLIANCE types are still formatted by Towny when modify_chat.enable is false.
  • Closes: TownyAdvanced/Towny#3568
