Added option to open AdventCalendar and its windows out of season. But beware! You can open different windows on different days. And more windows per day too! It is only to test calendar. I recommend set permission AdventCalendar.byPass to false after test it. Then it can occur some problem...

Changed the name of Plugin. I made mistake in plugin.yml, sorry. So at loading this plugin it will create a new folder with files. You have to copy them there. Or you can rename current folder to AdventCalendar

A full version will be available probably on the 30th of November. (Beta version is fully functional, too)

Deutsch language. Thanks to TheDragonLife to translate it

If you think that plugin is better than before, you can support me with PayPal donation.
