Add /dtoggle back

@buildcarter8 factoring many of the administrators have requested this command to be added back, I'd highly suggest adding it. I'll increase productivity and will allow us to toggle DiguiseCraft with the commands we've grown and love. I'd highly suggest you to rethink your decision.   Please rethink your original decision on #113
Merge pull request #117 from zD12/patch-50
