#2 dj commands do not work properly

[Gaudeamus]

!show dj will show "<%GSCBot> Usage: !show
[status/saves/vapes/dj/song]" instead of the dj name.

!dj <dj name> will only work the first time script is
run and will save the first entry. Any attempt to
change the dj after will result in the original dj
being retained but the message <%GSCBot> DJ set. is
still shown on any following change attempt.
