v1.0.3: Fix MOTD Hex color issue on SpigotMC and config loading problems

This version fixes a few issues that got reported on my Discord Server, but also adds a minor safety-check.

Fixes

• Fixed HEX color issues for MOTDs on a SpigotMC server.
• Fixed a edge case issue where an exception is throwing while creating the config.yml

Improved

• Added safety check for when the PaperMC version is used on a SpigotMC server. The plugin will print a warning and disable itself in a such case.
