[UX] Warn user if caps lock is on

[emilyclaudet]

At a workshop at Wayra on 19 September, there was a kid that was frustrated because they had caps lock on and none of the commands worked. Could there be a warning in Terminal Quest when the system detects caps lock is on to turn it off again?

I can think of a couple of ways this could be addressed, however I would want to figure out a way that would show the student exactly how to check for caps lock as one of the first protocols for troubleshooting. The _nix temrinal doesn't warn of caps lock when commands are executed, which for windows student users, is very frustrating (as cmd.com, and command.com are case insensitive). Thoughts?
Maybe first try of command, do a chekc for case, and if its the correct command sequence, yet incorrect case, notify the player. You could also correct the problem on the fly easily enough, but that would impact the players learning that CAPS Lock is an item they need to be aware of. Thoughts?
