[Dillo-dev] Doxygen documentation online

Hi, I added the Doxygen documentation in the main website, with the Doxygen Awesome theme: https://dillo-browser.github.io/doxygen/index.html Here is the main overview: https://dillo-browser.github.io/doxygen/dw-overview.html It also includes the documentation of most C functions that was not being included due to "/*" comments instead of "/**" at the beginning of the functions. It is rendered directly from the Dillo git repository weekly, until I figure how to trigger a pipeline in a different repo. It seems Doxygen is injecting some Javascript for the index, but I think there may be a way to avoid it so it can be properly read in Dillo itself. For now I'm leaving it as-is. Best, Rodrigo.
