Feat: Include section / subsection in block names

[bmtcril]

Instructor feedback is that it's difficult to understand the context of a problem or video without knowing where it is in the course. Additionally several blocks may share the same name, so it's hard to know which one you're looking at. An easy way to put the blocks in context is to prepend the section / subsection number and sort by the name so the blocks show up in order.

We'll need to update the block_names dictionary and table to query rank by order, then update the Superset charts and filters to make sure they sort by the name.
