v1.2.1 - Fixes around lang and join message

This release makes the reminder message to claim an advent gift respect the time offset.
It also makes it possible to change lang.yml. There is a boolean allow-modification which defaults to false. When it is set to false, it will always overwrite this file. If it's set to true you can adjust the lang file. Make sure every entry in the plugins lang.yml is present! I do want to make this easier in the future
