Allow HTML posts

[raphaelbastide]

It could be nice to be able to post HTML or Markdown content as an article.
Format suggestions:

Awesome title
%% All you need is <a href="http://catgifpage.com">cats</a>! %%

or/and:

Awesome title
%% cats.txt

Note: % is an arbitrary choice

What do you think @bpierre ?

Yes good idea, a few open questions:

• Do we want to keep the syntax without any tags? A solution could be to check the extension (.jpg, .png, .gif, .txt, .md, .html, etc.)
• Do we want to allow strings in the posts.txt? We could detect this too (no extension at the end of the line, no http://, etc.).
• Do we want to allow multiline strings in the posts.txt itself (that would require some tag since we are using line breaks to separate the posts).

To remain simple an flexible, I suggest to:

• detect the tag (.txt, .html, .md) for the content, and include it
• allow single line html (string)
• do not allow multiple line html

Your thoughts?
