Use One2One relationship instead of inheritance
This allows to add and also remove the virtual features of a room

Introduce new model
Create migrations to migrate from existing to new model + a squashed version knowing only about the new model for fresh installations
Adapt admin views
Add django-betterforms as dependency to simply create a form allowing to generate rooms with optionally a virtual component in a single view and create that form
Add view to create rooms in that view and use instead of default django creation form
Use the new name/structure in templates
Move RoomForm to forms.py to make imports easier
Update batch creation of rooms

This resolves #150 and also resolves #179 since now rooms and virtual rooms (rooms with virtual features) are created using the same view

Upgrade django to 4.1
Upgrade django-timezone-field, django-simple-history, django-debug-toolbar and django-bootstrap-datepicker-plus
Upgrade mysqlclient
Remove obsolete pytz
Adapt timezone handling code to new interface of TimezoneInfo (part of python since 3.9 and backport included in 3.8)
Drop support for python 3.7 (since Django 4 requires >= 3.8)

This implements #183

This mostly implements #159
Introduce a new field that denotes the timestamp when the plan was published
Introduce admin actions to publish and unpublish the plan and set that timestamp accordingly
Prevent other means to change visibility of the plan
Use that timestamp to only highlight recent changes when they occurred after the plan was already published

Introduce a new generic view that can be used for all admin actions that require a preview/confirmation or a form to specify parameters
Change AK Orga Message deletion view to use this generic view instead of a manually adapted delete view

Make sure plan is hidden by default and allow to adapt/change this during the usage of the wizard
This fixes #115

The wizard is used instead of the normal built-in creation workflow
It consists of multiple steps to specify the most fundamental settings (especially the timezone), further settings, copying AKCategories and AKRequirements from existing events and activating the event once the basic configuration is done
The steps after the creation (first two steps) can be skipped
