Documentation for self-hosting

[tomscytale]

fixes #484

I'm not exactly sure if the jekyll team support this mode of operation but I figure this is the best way to find out.

I'm self-hosting a jekyll site for a small community group of non-technical users.
Ideally I'd like to use jekyll-admin as a simple front-end behind a nginx reverse proxy.
The generated site is also served by nginx and auto updated by jekyll serve.

I've added a page to the documentation showing the nginx and systemd configation files necessary to make this work.

Some minor corrections needed..

@tomscytale Thank you for the proposal, do you have a public URL to the server for demonstration..?

[tomscytale]

demonstration... I'm using http basic auth for the admin pages so I'd have to create a password and send it to you using a secure channel.

so I'd have to create a password and send it to you using a secure channel

Please don't bother then. I was only inquiring in the general sense..
