Add the needed base applications

[sveetch]

Current implementation has been limited to a tiny stack to ease progression. However in this state the cookiecutter is very limited and even it help to enhance bootstrapping new projects, it lacks of many common applications we use.

Here we list the base applications we should focus to add first:

• DjangoCMS this is probably the more complex to do since it involves many other related apps, it may even need to improve project-compose to manage applications priority for all parts (settings, urls);
• A file browser solution. Filebrowser grapelli is a fork that did have many durability issues, even it's always maintained, something more stable would be nice. django-filer is preferred and will be tried first;
• CKeditor (out of DjangoCMS since other application may need it also);
• Restore 'emencia_initial' feature #14
• django-apps/project_utils/ probably needs its own app since it may involve migrations and management command;
• Recaptcha;
• Fobi;
• Lotus as the new Blog solution;
• django-sendfile2;
• Crispy forms
• Add Django Rest Framework to available apps #59
• Cmsplugin-blocks but it will need to be updated to fit to Django4 and last cms
• Sitemap builders #33
