Level information additions (feature)

[TemperGrace]

On the replay endpoint, we have several pieces of information that are community contributed, namely a rating system and the facility to add comments:

It'd also be useful to have this functionality on the level endpoint pertaining to each unique level ID, so that the community could rate levels and/or leave comments with information.

Even more useful would be the ability to apply a subset of potentially curated tags such as "Apple" or "FF" or "Uphill" that could then be leveraged to present level filters that users could use to find appropriate levels for a tag they're interested in playing. For example, someone looking to finish every tagged FF or Pipe might find that feature very useful, whereas currently we need to do a significant amount of memory work, manual updating & ongoing research to enable these sorts of projects. Such a system would still require a significant amount of up-front work but would result in a far more manageable and useful result with less maintenance required.

Side note: the !rec 10 and !lev 10 pretend commands from EOL chat feeding into the level/replay rating systems automatically would be a very interesting way to populate this data more readily.
