Maven SiteDoc support: Permit publishing HTML on the Wiki

Maven has a comprehensive site documentation system which uses the maven-site-plugin (and other plugins, such as maven-plantuml-plugin, cobertura-maven-plugin, maven-javadoc-plugin etc.) to generate HTML documentation from a slush of markup languages and resources.

The result of running mvn site is generated as HTML and corresponding resources (images, CSS etc.). I used to simply check in the result of the Maven Site documentation in the wiki - but nowadays Bitbucket does not serve HTML pages with the "text/html" mimetype implying that the site documentation is not visible.

Could you guys please re-introduce support for premade HTML so we can use the Maven site documentation generated by our project as our wiki documentation?
