Describe and/or add load_module directive

[gpip]

Since nchan is being built as a dynamic module here, do you think it would be a good idea to mention that

load_module modules/ngx_nchan_module.so;

should be added to nginx.conf?

I initially wanted to keep the file "vanilla" to the upstream but I recon the README is not very helpful at the moment.

Also had this problem. For me, the easiest solution was to add

RUN echo -e "load_module modules/ngx_nchan_module.so;\n$(cat /etc/nginx/nginx.conf)" > /etc/nginx/nginx.conf

line to my Dockerfile
