Add doc specific features to each project

[plaindocs]

• toc support
• reuse ?
• syntax highlighting
• markup used

[infotexture]

Those would all be useful things to see at a glance on each card.

As the list grows, it might be nice to be able to filter by those categories too, so “show me the ones that support MyFavoriteMarkup and syntax highlighting”.

(For something less straightforward like reuse mechanisms, that could be trickier, as each tool will offer varying concepts and degrees of support, so descriptions of those wouldn't work well with enumerated lists.)

[plaindocs]

Absolutely with you on all of that.

Even a binary does/does not support reuse would help. But I hope most do nowadays.
