Subject: Changed way of generating HTML
X-Git-Url: https://git.p6c8.net/pcdenotes.git/commitdiff_plain/69d7df229ddc5c993178928ad91f3273080da42c?hp=c72b86bdd8c5a7b826a5b02cfbc1928c8bd8d509

Changed way of generating HTML

-  Use python-markdown directly without django-markdownify
- Don't use linebreaksbr template filter
- Linebreaks are now created using <p> and so on
- blockquotes work now (they didn't work because of linebreaksbr)
