stub for Kac-Moody group, in order to record some references

I have added the statement of the theorem that the delooping $B G$ of every Kac-Moody group $G$ is the hocolim over deloopings of Lie groups. This is due to Kac, 1998, thought currently I am not sure what the reference is.

I have also added the remark: this implies that we naturally have a smooth refinement $\mathbf{B}G$ for every Kac-Moody group! This wasn’t clear to me before.
