Fix escaped underscore \_ names to be displayed in escaped mode.

• added a purename method that does the same as prettyname, but does not escape the text.
• added a purelinkto method that does the same as fulllinkto, but does not escape the linked text.
• documented.

Thx for the PR.

I away from this part of the code since a long time, so let's try to re-put this in mind.

The issue is about _ which is escaped in "link" and "prettyname".
We "escape" _ to avoid issue with markdown and @{}.

If I'm right I think we should not escape in fulllink and prettyname.
And just fix format function in template engine.

Does it make sense ?

I think it does. However, this may require changes in a lot of places.
I have started to dive into this code heavily. I am adapting the code to support the W3.css styling framework. This allows to remove those lists of types and properties and make them clickable.
Also I want later the pages to show the inherited class hierarchy. Which is a challenge as the types are located per _File record.
Modifying the templates etc. to W3.
I learn a lot by doin this. It is amazing what has been done. Especially with meta-lua.
We'll let it rest for the moment until I get a better understanding where those change points are to avoid the escaping.

There's is another burning issue. Problems with the escaping in hyperlinks is one. But what about markdown that contains A2A_CARGO_DISPATCHER...
The CARGO shouldn't be in italics...

I thought my idea will change less code.

I think this is a bug in markdown.lua library.
Maybe this fixed in a more recent version of https://luarocks.org/modules/mpeterv/markdown

I'll carefully evaluate your recommendation. But right now I wanna get that w3.css implemented.
