Sorry, for the many updates now, but I guess you all want to have the plugin working when it's time to open the first advent door...

- fixed an example in the generated config.yml
- removed console debug logging parts
- fixed the inventory of the advent calendar
- made the result of an item spawning able to be picked up again

But remember, complex code is more likely to contain bugs!

- fixes an important feature: month detection

- fixed a small little color bug in one of the english messages
- added support for minecraft 1.16.1 and minecraft 1.16.5

- added "config-version" in config file for future updates
- moved content from items.yml to config.yml
- removed items.yml-File
- removed debuging messages from console on startup
- default items are not generated into config file like intended again

Rembember that nothing is perfect. Expect some bugs (and report them if you find any) !

- Added testmode function (toggled via '/adventscalendar testmode')
- improved stability
- added and improved language support

Fixes an important saving issue
