New command to get information on unlocked exercises

[divagant-martian]

I can't seem to find a way of getting information on the tracks I'm involved. In particular, it would be nice to get information on the exercises that I'm solving at the moment, and which ones are unlocked. I know something similar is the output you get once a correct solution is submitted but unless you save that output somewhere, there is no way to get it again from the command line. It can also become inaccurate (by solving problems in other computers, or if the set of problems changes)
