v1.2.1 - Various improvements

• Improved the port section of the configuration. This might need to be re-configured during if you update the plugin, causing the plugin to disable itself when you first load it after an update
• Added new configuration option: gui > questpreview > enabled. It's enabled by default, but you can disable it if you prefer not to use the GUI for quest previews.
• Further improve data loading, making it safer
• Improve the /questadmin load command
• Fix compilation mistakes, which caused some conflicts with the GUI library or the plugin not loading on some servers, if that GUI library was not found.
• If you have the notnot.quests.admin permission, you now automatically inherit the notnot.quests.use permission
• Other internal improvements
