Option for command aliases

Writing challenge everytime is not fun. Better alias would be chall.

I see chal is an alias. I would suggest adding chall to the list and documenting it.

Gonna start updating this bot again haha, I've added "chall" as an alias. I will leave this issue open in case anyone else wants other aliases.
