Discourse Comments integration

[Mte90]

Ref: getnikola/nikola#3689

So I started working but some stuff is not clear to me.

So my needs are just 2:

• I need to check if the article has a parameter discourse_thread and get that value
• Print in the bottom in the comment section a HTML/JS code

So right now I saw that hooks are just 6 https://getnikola.com/extending.html#toc-entry-16 and no one of them is useful for me to print in the comment section.
It would be useful to have something to access the macro comment_link_script to print what I need but I didn't find anything. I see the cactus_comment instead use template files but I am not sure if this create troubles with themes.

Instead how to read a field in the article I didn't find a plugin that do that to replicate the code.

I have some doubts if it is the case to integrate it on theme side or by plugin. Or a plugin that is not a comment system but a task generator.

PS: the code is not yet tested.

Comment systems cannot be plugins. Instead, they should be part of Nikola core (they are just templates). Please convert your changes into Mako templates and open a pull request for getnikola/nikola.
