Support blogging from the site.

In an effort to make publishing content to the site easier, we should migrate blog posts to the database. We can make a markdown/wsywig editor available for use like we've done for admin tools.

I wonder how powerful it can be to enable EEF members blog posts (with moderation, of course) to EEF website. To give an example, some Erlang Solution blogs are simply incredible, and are used as manuals, - for example, famous https://www.erlang-solutions.com/blog/how-to-analyse-a-beam-core-dump/

I have a number of potentially interesting posts that can bump EEF website traffic and recognition in general, but right now markdown format is very limited (how do I add an image?) and it creates higher than desired friction.
