Display some indication of working while fetching oof leaderboard

[activexray]

Leaderboard is slow, sometimes when getoofs is called, it seems like it didn't work, but its just lag in sorting the results.

Potential solution is to create a message saying Sorting Results or something and delete the message once the results are ready to be displayed.

If you do this with slash commands it'll do this for you.

As in, turn the interactions part of it into slash commands? Is that easy to do in Discljord?
