LRDOCS-522 Convert properties files to HTML

Hi Hugo, here is the main class we'd like to use for converting properties files to HTML.

You can run it from liferay-portal/ with these arguments:

properties.file.path=./portal-impl/src/portal.properties properties.dest.file.path=. properties.title="Portal Properties" properties.toc=true

Please see LRDOCS-522 for example results, if you wish.

Thanks for reviewing this for us.
