Allow to add Views with more than one word with kivymd.add_view function

[krille90]

Description of the problem

Currently when creating views via kivymd.add_view, only views with one word, e.g. NotificationScreen, will be added correctly. When you try to add a view with the name NotificationSettingsScreen, all classes in the folders Model, Controller and View will be added. However, it won't be added in the screens.py(and no error / warning is thrown).

Describe the algorithm of actions that leads to the problem

In the file kivymd/tools/patterns/add_view.py (line 158ff) there is a restriction for only allowing one word screens:

if res and len(res) == 2 and res[-1] == "Screen":
                    screens += (
                        "\n    '%s': {"
                        "\n        'model': %s,"
                        "\n        'controller': %s,"
                        "\n    },"
                        % (
                            f"{res[0].lower()} {res[1].lower()}",
                            f'{"".join(res)}Model',
                            f'{"".join(res)}Controller',
                        )
...

Reproducing the problem

First create an kivymd MVC project. Then type in the following in commandline:

> kivymd.add_view MVC . NotificationSettingsScreen 

In the end, have a look into the screens.py, the imports are there, but not added in the screens dict.

Screenshots of the problem

Here you can see, that NotificationSettingsScreen wasn't added to the screens dict in screens.py

Description of Changes

I changed above code to allow multiple words:

if res and len(res) >= 2 and res[-1] == "Screen":
                    screens += (
                        "\n    '%s': {"
                        "\n        'model': %s,"
                        "\n        'controller': %s,"
                        "\n    },"
                        % (
                            f'{" ".join(res).lower()}',
                            f'{"".join(res)}Model',
                            f'{"".join(res)}Controller',
                        )
...

Screenshots of the solution to the problem

Here you can see, that it is now added properly.

Code for testing new changes

This module needs to be completely rewritten in accordance with the new API version 2.0.0

[krille90]

I understand, although I don't seem to have any issue with using this module using 2.0.x.
I think merging wouldn't be much of a problem though as it's quite the small change and a rewrite of the module will still take some time.
