DOC: intro: adjust the numbering of paragrams to keep the output ordered

The HTML version appeared with sections in a different order where
3.3.10..3.3.16 were placed between 3.3.1 and 3.3.2. This patch just slips
them into an intermediary section so that we now have "basic features",
"standard features", and "advanced features".
